Question

which formula is used when we have to find the area of the triangle band the height and base of the triangle is not given​

Answer 1

$\huge\star\underbrace{\mathtt\red{A}\mathtt\red{n}\mathtt\red{s}\mathtt\red{w}\mathtt\red{e}\mathtt\red{r}}\star\:$

What is the formula for finding the area of a triangle?

So, the area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle. Example: Find the area of the triangle. The area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle.

What is an area formula?

L is the length, W is the width and H is the height. A is the area of the base, h is the height.
