Holly has a rectangular garden that measures 12m by 14m. SHe wants to increase the area to 255m^2 by increasing the width and the length by the same amount. What will the dimensions be of the new garden ?
-solving that involves quadratic equations
New width = 12 + x
New length = 14 + x
Area = (12 + x)(14 + x) = 225
