Question

Find the area of the irregular figure. Round your answer to the nearest hundredth if necessary.

Answer 1

Explanation:

Area of the figure = Area of semicircle + area of rectangle

Area of semicircle:

d = 14 mm

r = 14/2 = 7 mm

Area = (1/2)πr²

`=(1)/(2)*(22)/(7)*7*7\\`

=11 *7

= 77 mm²

Area of rectangle:

length = 14 mm

Width = 10 mm

Area = length *width

= 14 * 10

= 140 mm²

Area of the figure = 77 + 140 = 217 mm²
