Question

The height of a triangle is twice the length of its base. The area of the triangle is 50m^2. Find the height and base to the nearest tenth of a meter

Answer 1

A = 1/2 b h
Given: The height of a triangle is twice the length of its base
so h = 2b
so
A = 1/2 (b)(2b)
A = b^2
area of the triangle is 50m^2
b^2 = 50
b = √50
b = 7.1

h = 2b = 50


answer
the height = 14.2 m
and
the base = 7.1 m
