Solve the quadratic equation using square roots

2√5

Step-by-step explanation:

You were on the right track.  Just move all of the numbers to one side, then take the square root of both sides.  After taking the square root of both sides, you should get x = √20 , then you can simplify √20 into 2√5.

∞ this is your sign

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.'
