Question

The area of a square mirror is 256in^2. A rectangular mirror has a width the same as the square mirror's width. Its length is two inches longer than its width. What is the area of the rectangular mirror?

Answer 1

256 = l×w

l = 2 + w

substitute the "l" in the first equation with the second equation (2+w) and solve for "w". Once you find it, plug into the second equation to find "l". Use the area formula for rectangles to find the area. Hope this helps!
