You can put this solution on YOUR website! A right triangle has a perimeter of 36 cm and an area of 54 cm squared. What are its dimensions?
---------------
Check for integer solutions first.
----
Area = a*b/2 = 54
a*b = 108
a & b = 9 and 12
9 + 12 + 15 = 36
====================
The hard way:
ab/2 = 54
-----
ab = 108
b = 108/a
Sub for b
-----------
a = 0 (Ignore)
(a - 9)*(a - 12) = 0
a = 9, b = 12
or vice versa
