A training field is formed by joining a rectangle and two semicircles, as shown below. The rectangle is 89m long and 70m wide.
Sindrei [870]

Step One

Find the area of the rectangle

Area = L * W

Area = 89 cm * 70 cm

Area = 6230 cm^2

Step Two

What is the formula for the two end semicircles?

Two semicircles = 1 whole circle

Area of any circle = pi * r^2

Step Three

Find the area of the circle

r = the width / 2     This may not be true. You need the diagram. If the circles are drawn on the length then use r = the length / 2

r = 70/2  = 35 cm

Area of circle = pi * r^2

Area of circle = 3.14 * 35^2

Area of circle = 3846.5

Step Four

Find the total area

The total area = Area of the rectangle + area of circle

The total area = 6230 + 3846.5

The total area = 10076.5 cm^2 <<<< Answer
