Samantha's homework is to determine the dimensions of her rectangular backyard. She knows that the length is 10 feet more than the width, and the total area is 144 square feet. Write an equation that Samantha could use to solve this problem. Then find the dimensions,in feet, of her backyard

w = width
w + 10 = length
Area = 144
A = Lw
144 = w(w + 10)
Solve for w
