Answer:
The first one : x^2 - 8x + 15 sq ft
Step-by-step explanation:
To find the ares you need to multipy L and W : (x - 3) x ( x - 5)
(x - 3) x ( x - 5)
(x times x) - ( 3x + 5x) + ( 5 x 3)
=x^2 - 8x + 15
If this helps you, please give brainliest!
(x-3)(x-5)=x^2-5x-3x+15=x^2-8x+15
Because the patio is a rectangle, so it's area is I.w=(x-3)(x-5)
