MACADAM
Parking Lot - First we split up the parking lot into two
rectangles so that we could find the area of it.
50 X 100 = 5,000ft2
First rectangle
200 X 300 = 60,000ft2
Second rectangle
60,000 + 5,000 = 65,000ft2
Total area of parking lot
It costs $1.50 per square foot for macadam
65,000 X 1.50 = $97,500
It costs $97,000 for macadam on the parking lot.
Basketball Courts – All we did was we found the total
area of the big rectangle that the two smaller rectangles
of the basketball courts lie in. We found the length and
width of the rectangle because we already knew the
dimensions of the two basketball courts and then we
knew that there was 25ft between the courts and 5ft all
the way around.
135 X 110 = 14,850ft2
Total area of big rectangle
It costs $1.50 per square foot for macadam
14,850 X 1.50 = $22,275
It costs $22,275 for macadam on the basketball courts.
Tennis Courts – All we did was we found the total area of
the big rectangle that the five smaller rectangles of the
tennis courts lie in. We found the length and width of the
rectangle because we already knew the dimensions of
the five tennis courts and then we knew that there was
10ft between the courts and 10ft beyond the courts.
240 X 98 = 23,520ft2
Total area of big rectangle
It costs $1.50 per square foot for macadam
23,520 X 1.50 = $35,280
It costs $35,280 for macadam on the tennis courts.
Walk Way-All we had to do was use the dimensions that
we already had which were 425 X 8 but there was a trick
and that was the bridge so we subtracted that and then
all we had to do was 405 X 8.
405 X 8 = 3,240ft2
Total area of walk way.
It costs $1.50 per square foot for macadam
3,240 X 1.50 = $4,860
It costs $4,860 for macadam on the walk way.
Total cost of Macadam- All we did was add up all of the
costs of the parking lot, basketball courts, tennis courts,
and the walk way.

CONCRETE
Shed- For the shed all we did was multiply the length x
width x depth in feet and then divided it by 27 to get
cubic yards.
25ft. x 50ft. x 1ft. = 1,250ft2
total area of shed
1,250ft.2 = 47yd.3
27
47yd.3
x 210
It costs $210 per cubic yards for concrete
$9,870
It costs $9,870 for concrete at the shed.
Pavilion- For the pavilion we did the same thing as we
did for the shed.
50ft. x 50ft. x 1ft. = 2,500ft.2 Total area of pavilion.
2,500ft.2 = 93yd.3
27
93yd.3
x $210
$19,530
It costs $19,530 for concrete at the pavilion.
Lavs- We did the same thing we did to the others.
10ft. x 20ft. x 1 ft. = 200ft.2 Total area of bathrooms
200ft.2 = 8yd.3
27
8yd.3
X $210
$ 1,680
The total cost for concrete of the bathrooms is $1,680.
Concession- We did the same thing as we did to the
others.
15ft. x 20ft. x 1ft. = 300ft.2 Total area of concession
300ft.2 = 12yd.3
27
12yd.3
X $210
$2,520
The total cost of concession is $2,520.
DIRT
SAND
Volleyball Courts- For this we multiplied the length x
width x depth in feet to find feet squared.
MULCH
Play Area- For the play area we multiplied the length x
width x depth in feet to find the area. Then we divided it
by 27 to find it in cubic yards.
50ft. x 50 ft. x .25 ft. = 625 ft.2 total area of play area
625ft.2 = 24yd.3
27
24ft.2
X $40
$40 per cubic yard.
$960
The total cost of mulch is $960.
FENCE
Tennis Courts - All we did was took the length of the big
rectangle that the tennis courts lie in and multiply it by 2
and then we did the same thing with the width. Then we
added those two numbers to get how many feet of fence
we need.
240 X 2 = 480ft
Length
98 X 2 = 196ft
Width
480 + 196 = 676ft
Total feet of Fence
It costs $1.80 per foot for the 14 foot high fence that
goes around the tennis courts.
676 X 1.80 = $1,216.80
It costs $1,216.80 for the total cost of fence around the
tennis courts.
Pool - All we did was took the length of the big rectangle
that the pool lies in and multiplied it by 2 and then we
did the same thing with the width. Then we added those
two numbers to get how many feet of fence we need.
46 X 2 = 92ft
Length
91 X 2 = 182ft
Width
182 + 92 = 274
274 – 20 = 254
Total feet of fence
(but then we had to subtract 20ft because of the LAVs)
It costs $0.55 per foot for the 8 foot high fence that
goes around the pool.
254 X .55 = $139.70
It costs $139.70 for the total cost of fence around the
pool.
Baseball field – All we did was added up all of the sides
of the baseball fields.

baseball field.

EXCAVATING
Excavating – All we did was take the whole land that the
complex was being built on and divided it into 8 different
shapes and found the area of each of those shapes. We
then added those numbers together to get the total area
of what was being excavated.
195,000.00

10,937.00
452,812.50ft2
Then we had to change that to square yards so we had to
divide 452,812.50 by 9 to get square yards.
452,812.50 ÷ 9 = 50,312.50yd2
It costs $8.00 per square yard for excavating.
50,312.50 X 8 = $402,500
It costs $402,500.00 for the total cost of Excavating.
GRASS SEED
Grass Seed – All we did was took the total square feet of
excavating and subtracted the total square feet of dirt,
macadam, concrete, mulch, and sand.
