Question

You have a rectangular yard that measures 16 feet long 14 feet wide. It is covered in grass except for the center, where there is a circular fountain with a diameter of 4 feet. What is the area of the grass portion of your yard? Round your answer to the nearest hundredth. is it (a) 131.43 ft.² (b) 173.74 ft² (c) 211.43 ft² (d) 263.74 ft²

Answer 1

First, get the area of the rectangular yard.
Area = L x W 
Area = 16 X 14
Area = 224 square feet

Get the area of the circular fountain.
Area = pi x r^2
Area = 3.1415 x (4/2)^2
Area = 12.57 square feet

Getting grass portion.
224 - 12.57 = (C) 211.43 square feet
