In this triathlon you do a 2k swim, a 43k bike
and a 10k run. How far overall do they travel?
In a 4x400m relay, each person runs it in 42.9
seconds. How long does it take the whole team
to finish?
Paula Radcliffe has the women’s record for
the marathon. She completed it in 2h, 15min
and 25 sec. The men’s record is 2h, 3min and
38 sec. What is the difference between these
two times?

LO: To be able calculate areas of rectangles and
rectilinear shapes. (Level 4/5)
Good if you can calculate areas by counting
squares.
Even better if you can work out rectangles area
using the formula.
Excellent if you can work out the areas of
rectilinear shapes.
Olympic Area
Counting Squares
A square cm has a length of 1 cm. We say that it
has an area of 1 cm2 ( 1 cm squared).
This rectangle contains six squares. Each of the
squares has an area of 1cm2, so the area of the
rectangle is 6cm2.
Questions
Count the squares, to find the area of the
Olympic boxing ring.

• ANSWERS
Have you spotted a rule that will help
you work out the area?
Length x Width
To work out the area of a rectangle or a square
you have to times the length by the width.
Example
An Olympic sandpit is 2.75m x 9m.
What is the area of the sandpit?

a shape.
Method 1
• Divide the shape into separate squares and
rectangles.
• Work out the area of each separate one and
then add them together.
Example
Compound Area
Method 2
• Imagine the area as a huge rectangle with a
shape cut out.
• Find the area of the large rectangle and
subtract it by the area of the part which is cut
out.
Example
Question 2
