Area of a rectangle = length times width

The factors of 63 are:

3 * 21

9 * 7

Perimeter = 2 times length plus 2 times width

The rectangle can't be 3 by 21 since its perimeter would be 6 + 42

The dimensions must be 9 by 7.

(2 * 9) + (2 * 7) = 18 + 14 = 32

He needs to draw a rectangle that measures 9 by 7.
