Question 857685: A rectangle with length L and width W has a diagonal of 10 inches. Express the perimeter P of the rectangle as a function of L. Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! diagonal = 10 in
l^2+w^2= 100
w^2=(100-L^2)
w= +/-
Perimeter = 2(L+W)
Perimeter = 2(L+/-sqrt(100-L^2))
