Question

Suppose the height of a triangle is tripled. How does this affect the area of the triangle? Explain

Answer 1

A' = 3A

Explanation:

The area of a triangle is given by :

`A=(1)/(2)* b* h`

Where

b is base and h is height

If height is tripled, h' = 3h

New area,

`A'=(1)/(2)* b* h'\\\\=(1)/(2)* b* 3h\\\\=3* (1)/(2)* b* h\\\\=3A`

So, the new area becomes 3 times the initial area.
