Question

This composite shape is a rectangle with a semicircle attached on one end. The diameter of the semicircle is 6 feet.What is the approximate area of this composite figure? Use 3.14 for pi and round to the nearest whole number. 46 ft 74 ft 88 ft 117 ft

Answer 1

We know that
area of the composite figure=area of the rectangle+area of semicircle

area of rectangle=b*h
b=10 ft
h=6 ft
area rectangle=10*6----> 60 ft²

area of semicircle=pi*r²/2
r=6/2----> 3 ft
area of semicircle=pi*3²/2-----> 14.13 ft²

area of the composite figure=[60+14.13]-----> 74.13 ft²-----> 74 ft²

the answer is
74 ft²
