Question

What is the area of the composite figure below? Round to the nearest tenth.

Answer 1

184.1

Explanation:

You have 4 different areas you need to look at. 1 half circle with a diameter of 8, a triangle with a height of 5, base of 6 and right angle, a rectangle with the measures of 8 and 9 and another rectangle with measures of 6 and 12

Circle:

`A = \pi r^(2) \\A = \pi 4^(2) \\A = 50.265`

Area of the half circle is 25.1325

Triangle:

`A = h(b)/(2) \\A = 5 (6)/(y) \\A = 15`

Area of the triangle is 15

Rectangle:

`A = wl\\A = 9*8\\A = 72`

Area of first rectangle is 72

Area of 2nd rectangle is using 6 and 12 = 72

Now add all together for your total area
