recall the formula for finding the area of a rectangle. define a variable for the width and set up an equation to find the dimensions of a rectangle that has an area 144 square inches, given that the length is 10 inches longer than its width.

width:
length:

Width: 8 inches

Length: 18 inches

Step-by-step explanation:

This is simple Systems of Equations:

{wl = 144

{10 + w = l

Use Substitution:

w[10 + w] = 144

w² + 10w - 144 [Distribute, then move −144 to the left side of the equivalence symbol]

[w + 8][w - 18]

When set equal to zero, you will get the ABSOLUTE VALUE DIMENSIONS above, since we are specifically talking about DIMENSIONS. Dimensions are NON-NEGATIVE.
