Question

What is the triangle's base, b?

Answer 1

In order to find the base

We apply the area of a triangle formula to find the base

We know the formula to find the area of a triangle is,

`A =(1)/(2)XbXh`

Here the area and the height is given

So the base is

`12 = (1)/(2) X bX3`

Substituting the values we get

`(12X2)/(3) = b`

`8cm = b`

Answer 2

A=1/2bh and b=2A/h so

b=2A/h =2(12cm^2)/3cm=8cm
