Question

If the base of a triangle is doubled then its area will be. ..... times of original area

Answer 1

Concept:

area of triangle= $\frac{1}{2}*b*h$

Given:

the base of a triangle is doubled

Solution:

We know that the area of a triangle is $\frac{1}{2}*b*h$. So, if the base is doubled then the area of the triangle will ultimately be also doubled. Because if $\frac{1}{2}*b*h$ is the area and the base are doubled then we get

$\frac{1}{2}*b*h\\\frac{1}{2} *2b*h\\b*h$

Hence, we have proved that if the base of a triangle is doubled then its area will also be doubled.
