    hints: Either 1. divide the area by the width to find the length, or 2. factor the area and see if the width is one factor, then the length is the other factor. \(\color{blue}{Example:}\) Area = 240, width = 15 Length = 240/15= 16 or area = 240 = 15*16 since the width = 15, then length = 16

    Okai we are given with the value for area right? But we also know that area= width * length So we can equalize the area to w * (x+15) right? w(x+15) = X^2 + 18x + 45 right? Did u get up to this point ?

    Yes, you need to factor the area to find the possible sides (See step 2 above). If you need help factoring, see for example: http://www.purplemath.com/modules/factquad.htm
