Question

the height of a triangle is 3 times its base if the are of the triangle is 216m2 find the measure of the base​

Answer 1

Answer:

let its base be x

let its height be 3x

Area of triangle = 216 m²

½ × b × h = 216 m²

½ × x × 3x = 216 m²

½ × 3x² = 216 m²

x² = 216 × 2 /3

x² = 144

x = $\sqrt{144}$

x = 12

base = 12 m

height = 12 × 3 = 36m
