Answer:
C. w² + 3w - 88 = 0
Step-by-step explanation:
Area of a Rectangle: A = lw
We need to figure out what l and w are:
l = w + 3
w = w
So now we know our 2 variables, we plug it into the area formula:
88 = w(w + 3)
88 = w² + 3w
The only way to find w is using quadratic formula or factoring:
w² + 3w - 88 = 0
