First name variables:

Width of rectangle = W

Length of rectangle = L = 2W + 3 (from "...length of a rectangle is 3 more than twice its width") ................ (1)

Perimeter of a rectangle = 2L + 2W = 2(2W + 3) + 2W

perimeter is 22

2(2W + 3) + 2W = 22

Solve for 'W' from above - then solve for 'L' from (1)
