Dimensions of an area?
A rectangle has an area of 154^2. It's length is 3 feet longer than its width. I know that Area= LW ,and have set up the problem as such:

Use these two formulas in your solution:
1) LW = 154^2
Now, substitute W+3 for L in equation one.
Now, distribute the W.
Now, subtract 154^2 from both sides
Now, factor the equation.
I'm not sure what the exact numbers are that fill in the __'s but from there you separate the two equations and work with the (W-__)=0 and solve for W. Then, you take that answer and plug it into the L=W+3 equation to find L. Hope I helped!
