Question 248305
Leg xy of the right triangle shown in the diagram below is twice as long as leg yz. if the area of the triangle is 36 cm^2, what is the length, in cm, of leg xy 
------------
Let yz = x
Then xy = 2x
---------------------
Area = (1/2)bh
36 = x(2x)
18 = x^2
x = 3sqrt(2)cm
----------------
2x = 6sqrt(2)cm
