Question

a triangle with a base of 9 meters has an altitude of 12 meters.which would give the area of the triangle

Answer 1

54
`m^2`

Explanation:

To find the area of a triangle use the formula a = 1/2bh

The altitude is the same as height so we can substitute 12 for h and 9 for b

Now the equation will become

a = 1/2 · 9 · 12

When you multiply it, it become 108/2 = a simplified to a = 54
