A=L*W
P=L*2W three sides
600m=L*2W
L=6002W
substitute in the area
A=(6002W)*W
A=600W2W^2
convert the eq. to vertex form y=a(xh)^2+k
A=2W^2+600W
complete the square
A=2(W^2300W+22500)+22500*2
A=(W150)^45000
w=150
substitute calculate....
L=6002w
L=600300 =300
dimension
150x300

A family wants to fence a rectangular play area alongside the wall of their house. The wall of their house bounds one side of the play area. If they want the play area to be exactly 400ft2, what is the least amount of fencing needed to make this? Round your answer to the nearest two decimal places.
