Answer:
Base = 12cm
Height = 24cm
Explanation:
Hello glittersplanet,
The formula for the area of a triangle is A = 1/2 b * h where A equals the area, b equals the base, and h equals the height. You are given the area in this problem.
Let the following conditions apply:
Base = x
Height 2x <-------Problem states the height is twice its base, correct?
Therefore:
A = 1/2 b*h
144 = 1/2 (x)(2x)
Simplify by removing the fraction by multiplying through by 1/2 and you are left with x^2 correct? Therefore:
144 = x^2
x = √144
x = 12
Therefore, base = x = 12 while height = 2x = 2(12) = 24
