Geometry question- eva lewis wants to put an underground sprinkler system in her back yard. the yard is a rectangle that is 56ft wide by 85ft long and she wants piping around the perimeter and through the diagonal of her yard. about how many feet of water pipe will eva need?

what is the starting amount? the question is not clear sorry.

step-by-step explanation:

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
