width (w) = w
Length (L) = 3w + 4
Area (A) = L x w
25 = (3w + 4)w
25 = 3w² + 4w
0 = 3w² + 4w - 25
w = 
w ≈ 2.3, w ≈ -3.6 (width cannot be negative!)
w ≈ 2.3
Length (L) = 3w + 4 = 3(2.3) + 4 = 6.9 + 4 = 10.9
Answer: width=2.3, Length=10.9
Firstly, expand the equation.

Next, move the variable x to the left and all the constant to the right.

Then, solve for x.
