Answer 1

Answer: $39ft^2$

Step-by-step explanation:

This is a rectangle missing a piece which looks like a triangle.

Find the area of the rectangle and subtract the area of the triangle.

Rectangle:

$A=l*w\\A=(9ft)(5ft)\\A=45ft^2$

Triangle:

$A=\frac{hb}{2}\\ A=\frac{(3ft)(4ft)}{2}\\ A= \frac{12ft^2}{2}\\ A=6ft^2$

Now subtract the area of the triangle from the area of the rectangle.

$45ft^2-6ft^2=39ft^2$

Answer 2

The answer is 39ft squared
