The figure is divided into a semi circle and a trapezium. Thus, the area of the figure would be the sum of the area of the semicircle and the trapezium

The formula for finding the arae of a semicircle is expressed as

Area = 1/2 x pi x radius^2

From the figure,

radius = 3

pi = 3.14

Area of semicircle = 1/2 x 3.14 x 3^2

Area of semicircle = 14.13

The formula for finding the arae of a trapezium is expressed as

Area = 1/2(a + b)h

where

a and b are the length of the top and bottom

h is the height

From the figure,

a = 8, b = 11, h = 6

Area = 1/2(8 + 11)6

Area = 1/2(19)6

Area of trapezium = 57

Thus, the area of the figure is

14.13 + 57

= 71.13

Rounding to the nearest whole number,

the approximate area is 71 square units
