I need this wood problem answered and how you got the answer

Question

The area of a triangle is 75 square meters. The altitude of the triangle is 5 meters longer than the base of the triangle. Find the base and the altitude of the triangle.

Answer 1

Amy,Amy,Amy... please post ONE copy of the problem....

Area = (1/2) base * height

75 = (1/2) (x+5)x where x is the base measure

150 = x(x+5)

x^2 + 5x - 150 = 0

( x+15 )(x-10 ) = 0

x+15 = 0 results in negative measures...

x=10 is the base measure

so base is 10, height is 15
