If x = 15 inches, y = 8 inches, z = 11 inches, and h = 6 inches, what is the area of the triangle above?
48 inches2
45 inches2
42 inches2
40 inches2

Actually to find out the area of the given triangle we don't need to know the measurements of y nor z. Base length x and height h are enough as the formula for triangle's area is 1/2xh.

A = 1/2 * x * h
A = 1/2 * 15 * 6
A = 15 * 3
A = 45

Area of the given triangle is 45 square inches (answer B).

If x = 15 inches, y = 8 inches, z = 11 inches, and h = 6 inches, what is the area of the triangle above?= 42  i think 
hope it helps 

I'm not sure exactly but my best guess would be 1/4
