Then.look at the problem, and see that 90 is three times 30.
-- 90 is 300% <em><u>of</u></em> an entire 30 .
-- To go from 30 to 90, you have to increase the 30 <em>by</em> 200% of itself.
First find the length of the longest leg
x^2 = 13^2 - 5^2 ( by the Pythagoras theorem)
x^2 = 144
x = 12
Area of the traingle = 1/2 * base * height
= 1/2 * 5 * 12
= 30 units^2
.7 & .700 are the same number
