Question 420191: The base of a triangle is 2 MORE than TWICE the height of the triangle. Find the measure of the base and the height if the area is 20ft2 (20 feet square). Answer by edjones(8007) (Show Source):
You can put this solution on YOUR website! b=2h+2
.5bh=A
.5(2h+2)h=20
.5(2h^2+2h)=20
h^2+h=20
h^2+h-20=0
(h+5)(h-4)=0
h=4, b=10
