Simple algebra applied to rectangle.

A = 55 yd^2
L = length
w = width
k = 4 yd
m = the factor, 3
-

.
.
Substitute for L in the A equation.




WHAT NEXT?
Use the general solution of a quadratic equation to solve for w. Substitute the given values for k, A, and m and compute w. Use the now found value of w to compute L.
