Answer:

Area of question = 336.14

Explanation:

Step One

Find the area of the rectangle, ignoring the semi-circles at each end.

L = 35 cm

W = 14 cm

Area = L * W

Area =35 * 14 = 490 cm^2

Step Two

You will drive yourself a little mad is you don't realize that the two end sem-circles = 1 whole circle.

Find the area of the circle

r = d/2

r = 14/2

r = 7

Area = pi * r^2

Area = 3.14 * 7^2

Area = 3.14 * 49

Area = 153.86 cm^2

Area of question

Area of the rectangle - Area of the circle

490 - 153.86 = 336.14 cm^2
