WHAT IS THE AREA OF THE GRASSY SPACE? LOOK BELOW FOR QUESTION! THANKS IN ADVANCE!

We subtract the entire area of the rectangle by the area of the pool.

We will use the foiling method:

(x-4)(2x+7)= 2x^2+7x-8x-21=2x^2-x-21

Then we subtract, 3x^2-14x-5-(2x^2-x-21)

Simplifying we get:

x^2-13x+16

x^2-13x+16 is the area of the grassy space.

I hope this helps!
