Question 242114: the base of a triangle is 5 cm greater than the height, the area is 33 cm^2, what is the height and length of the base, can you walk me through this? thanks so much Answer by solver91311(16868) (Show Source):
Let represent the measure of the base. Let represent the measure of the height.
We are given that
The area of a triangle is given by
But since we know the value of in terms of , we can write an equation for the area as a function of the height:
But since we are given the area, we can write:
Simplify and put into standard form:
Now all that is left is to solve the factorable quadratic and select the positive root for the measure of the height. The measure of the base then follows directly.
