Question

Find the area of the figure. Round to the nearest tenth if necessary.

Answer 1

Answer:

100ft^2

Step-by-step explanation:

As there is a semi circle at the border whose diameter is same as the length of the rectangle on the other end. (i.e 7.4ft)

So, the radius will be,

7.4/2 = 3.7 (is the distance between point to the end of the circle, i.e radius)

So,

Area will be,

14.4ft - 3.7ft (semicircle distance to got whole rectangle)

= 10.7 (Breadth)

Area of rectangle = L×B = 7.4×10.7 = 79.18

Area of semi circle = 1/2(πr^2) = 1/2×22/7×(3.7)^2 = 21.51

By adding both the area,

79.18 + 21.51 = 100ft^2 is the area of whole figure.
