Question

The base of a triangle is half its height and area of the triangle is 36 cm2. The length of the base of the triangle is

Answer 1

Step-by-step explanation:

We know that the formula for area of triangle is A= 1/2×b×h

It is mentioned in the question that b is half of h

b= 1/2h

Area of the triangle is given to be 36cm^2

36 = 1/2× h/2×h

144= h^2

h = 12cm ( h cannot be -12 as height is never negative)

Base = height/2

Base = 6cm
