Question

The area of a rectangle is 99 in². The length of the rectangle is 2 in. longer than the width.

What is the width of the rectangle?

stamp · Answer

area = length *width, or a = lw

area is given A =99, length is given l = 2 +w, and width is simply w.

substituting we realize:

a = lw

99 = (2 +w) w

99 = 2w +ww

ww +2w -99 = 0

Solve w
