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

Answer:

w^2 +3w -88=0

Step-by-step explanation:

l = w+3

w = width

A = l*w

A = (w+3) *w

Distribute

A = w^2 +3w

We know the area is 88

88 = w^2 +3w

Subtract 88 from each side

0 = w^2 +3w -88
