B.) Determine the dimensions of the plot of land that has the least area.

C.) what is the least area?

Well xy is 1000

Area= pool

Area= (x+3)(y+3) but y=1000/x

1)Area= (x+3)(1000/x +3)

Least area? Take dA/dx, set to zero, and solve for x. Then solve for y.

least area is the area in 1) above with the x you found.
