using the definite integral to prove the area of a right triangle

[bluester105]

use the definite integral to prove that the area of right triangle of altitude a and base b is (1/2)ab (hint:make the vertices of the triangle to be points (0,0), (b,0) and (b,a) draw a picture to help you...


okay so i know im not the smartest person in the worl and it may just be because i hate my teacher but im completely confused with this problem so i would really really really appreciate any help i can get. thanks.
