The perimeter and the area of a rectangle have the same numerical value. If the length of the rectangle is 4 units, what is the width in units of the rectangle?
Record your answer and fill in the bubbles on your answer document. Be sure to use the correct place value.

Formula

2*(L + W) = L * W

Given

W = 3

Solution

2*(L + 3) = 3*L

2L+ 6 = 3L                      Subtract 2L from both sides

2L - 2L + 6 = 3L - 2L      combine

6 = L

The length is 6 units long.
