Question 706371: A rectangular garden is 7 ft longer than it is wide. Its area is 494 ft2. What are its dimensions? Answer by filboi(35) (Show Source):
You can put this solution on YOUR website! (A)rea = (L)ength x (W)idth = 494
L = W + 7
By substitution,
A = (W+7)(W) = 494
By factoring, we get:
(W-19)(W+26)=0; W=19, W=-26(Disregard this since there is no negative width)
So the dimensions are L=19+7=26ft and W=19ft.
