Question 333564: We know that the area of a triangle is (b*h)/2, b being its base, h being its height. If a triangular sail has an area of z2 + 6z + 8 square meters and a height of z + 2 meters, an expression that will give the length of the sail's base is:

You can put this solution on YOUR website! We know that the area of a triangle is (b*h)/2, b being its base, h being its height. If a triangular sail has an area of z2 + 6z + 8 square meters and a height of z + 2 meters, an expression that will give the length of the sail's base is:
-------------------
Area = (1/2)bh
2(z^2+6z+8) = b(z+2)
---
b = 2(z^2+6z+8)/(z+2)
b = [2(z+4)(z+2)]/(z+2)
b = 2(z+4)
b = 2z+8
