The formula for the area of a triangle is: onehalf(b)(h) b:base and h:height For example: A triangle is 4 inches tall and 3 inches wide. What is the area of the triangle? Answer: onehalf(b)(h) onehalf(3)(4) onehalf(12) 6 So, the area of this particular triangle is 6 inches squared.
3/4
3 - x
(3 + -8) - 8
