Question

How do you find the area of a triangle with base 10 cm and altitude 9 cm?

Answer 1

`= color(blue)(45cm^2`

Explanation:

The area of a triangle when the base `(b)` and altitude/height `(h)` are given is

`= color(blue)(1/2 xx b xx h`

Here, `base = 10cm`
`height = 9cm`

Area = `1/2 xx 10 xx 9`

`= 5xx9`

`= color(blue)(45cm^2`
