The answer would be (8pi +12) in^2
This is because to solve for the semicircle the equation is:
1/2*pi*r^2 1/2*pi*16
And the equation for the triangle is:
1/2*hb*h 1/2*8*3

The length of a rectangle is eight more than twice its width. The perminiter is 96 feet . find the deminsions. With the variable

Valentin [98]

Step-by-step explanation:

lenght = x + 8

width = x

$perimeter = 2(x + 8) + 2(x) \\ 96= 2x + 16 + 2x \\ 4x = 96 - 16 \\ x = \frac{80}{4} \\ x = 20$

then

Lenght = x + 8 = 20 + 8 = 28

Width = x = 20
