Question 757698
I need help in solving this problem please 
one side of the rectangle is 18 inches and the diagonal is 27 inches what it's the length of the other side of the rectangle (answer in radical form please)
--------
Draw the picture.
You have a rectangle with base = 18 and diagonal = 27
Let the height be "x".
-----
Use Pythagoras to solve for "x":
x^2 + 18^2 = 27^2
x^2 = 405
x = sqrt(405)= sqrt(81*5) = 9*sqrt(5)
