A playground is shaped like a rectangle with a width 5 times its length (L). What is a simplified expression for the distance between opposite corners of the playground?
A.) L square root 26
B.) 5L
C.) 26L^2
D.) 6L
Thanks

W= 5L
So the side lengths are 5L and L.
by definition of a right triangle (5L)^2 + (L)^2= ?
25L^2 + L^2= 26L^2
This matches choice C. 
C is not correct.
