Question 1133636

you have  square patio, so the length and the width are same

the area is {{{A=L^2}}}

if {{{A=256ft^2}}}, we have

{{{L^2=256ft^2}}}

{{{L=sqrt(256ft^2)}}}

{{{L=16ft)}}}

now find the length of diagonal which is hypotenuse in right triangle made of two sides of the square and diagonal

{{{d^2=L^2+L^2}}}

{{{d^2=2L^2}}}

{{{d^2=2(256ft^2)}}}

{{{d^2=512ft^2}}}

{{{d=sqrt(512ft^2)}}}

{{{d=22.63ft}}}->that is how long will that pipe be
