Question

Find the missing dimension of the triangle.

Answer 1

b=7m

Explanation:

The given triangle has height 8 m, base b m, and area ,28 m².

The area of a triangle is given by:

`A= (1)/(2) bh`

We substitute the given information to get:

`28 = (1)/(2) * b * 8`

Let us simplify on the right side.

`28 = 4b`

You can now divide both sides by 4

`(28)/(4) = b`

`b = 7`

Therefore the base is 7 m.
