Question

A rectangle has an area of 12 m find the perimeter in terms of one of its lengths

Answer 1

Area = length x width
Perimeter = 2(l + w)

Let's imagine one of the sides is 6. The other side would have to be two, and the perimeter would be 16.

If one of the sides is 4, the perimeter would be 14.

If one of the sides is 1, the perimeter would be 26.
