Question

A rectangle's perimeter and its area have the same numerical value. The width of the rectangle is 3 units. What is

the length of the rectangle in units?

Answer 1

l = 6.00

Explanation:

So A = l x w and P = 2l + 2w, they say they are equal to l (w) = 2l + 2w and we know that w = 3 so

3l = 2l + 2(3), so l = 6.
