Question

The area of a particular triangle is 30m^2 . If the base length of that triangle is 15m, what is the height of that triangle?
A = 1/2 bh Solve for h and then substitute to find the height.

1 point
h = 1/2 Ab; h = 225 m
h = 2Ab; h = 900 m
h = (2A)/b; h = 4 m
h = 1/2 A/b; h = 1 m
h = A/2b; h = 1/2 m

Answer 1

Use A = (1/2) b h. Solve: h = (2A)/b. Substitute A = 30, b = 15: h = (2·30)/15 = 60/15 = 4 m.

Correct choice: h = (2A)/b; h = 4 m.
