A house has two rooms of equal area. One room is a rectangle 4ft narrower and 5ft longer then the square one. Find the area of each room.
Please explain to me what to do because i am confused. Thanks

Square room is x by x with area x^2.
The rectangular room is (x  4) by (x + 5.
Therefore, x^2 = (x4)(x+5)
I bet you can take it from here.
