How to find area of triangle

Answer 1

❒ Question -:

How to find the area of a triangle?

❒ Explanation -:

Triangle :

A polygon which has three sides is called a triangle.

Formula :

Assume a rectangle ABCD and let the height be h and base be b.

If we draw a diagonal from one vertex, it will break the rectangle into two congruent or equal triangles. The area of each triangle is half the area of the rectangle.

The area of the triangle ABC is
`(1)/(2)` × base × height.

`\star \small\boxed{ \rm{ Area \: of \: a \: triangle = (1)/(2) × Base × Height}}`

This formula comes from the area of a rectangle. A triangle is half as big as the rectangle that surrounds it, that is why the area of a triangle is one-half base times height.

Answer 2

`\displaystyle A =(B*H)/(2)`

Explanation:

To find the area of a triangle, we can use the formula of:

`\displaystyle A =(B*H)/(2)`

This formula comes from the area of a rectangle, because a triangle is half a rectangle.
