The perimeter of a rectangle is 36ft, and the area of the rectangle is 72ft^2 . How do you find the dimensions?
You must write a system of equations to represent the problem.
The formula for perimeter of a rectangle is
We can now eliminate the denominators since all fractions are equal.
This is a trinomial of the form
Since the length can be the width and vice-versa, the sides of the rectangle measure 12 and 6.
Hopefully this helps!
