Matilda uses the polynomial identity (2x−y)2=4x2−4xy+y2 to show that 18² = 324. What values can Matilda use for x and y?

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
