Area & Perimeter SHAPE OVERVIEW Rectangle Triangle Hexagon Circle Parallelogram Trapezoid Square Pentagon Perimeter of a Rectangle 2 4 To calculate the perimeter of an object or space, you will need to add up all of the outside measurements. 2 + 4 + 2 + 4 = ________ Try to find the perimeter of these rectangles. 1 6 2 3 2 5 4 3 Find the perimeter of these squares. 25 5 12 16 8 Find the perimeter of these triangles. 5 3 5 5 5 4 10 8 3 3 3 6 Tricky Perimeters (Look carefully.) 3 You will need to remember which sides to add and the values for each side. 2 2 2 2 AREA You will use different formulas for each type of shape when finding area Each answer will require you to use the measurement given, and it will always be squared…ex.) 9 ft.2 Area of a Rectangle L W A=LxW The area formula for a rectangle is length x width Find the area of these rectangles. 1 6 2 3 2 5 4 3 Area of a Square A=SxS You find the area of a square by multiplying the side by itself. S Find the area of these squares. 25 5 12 16 8 Area of a Triangle H B Finding the area of a triangle is different. A = ½ (B x H) Find the area of these triangles. 3 4 7 5 8 2 3 6 AREA OF A PARALLELOGRAM H B A=BxH (base x height) Find the area of these parallelograms. 2 4 3.5 7 14 19 AREA OF A TRAPEZOID B1 H B2 A = ½ H (b1 + b2) ½ Height (base 1 + base 2) Find the area of the trapezoids. 23 12 14 31 16 9
