Question

The triangle shown below has an area of 20 units squared. Find the missing side if the height is 8

Answer 1

5 because the formula for a triangle is (l w) divide by two and you get the area so when you do the formula backwards you get 5

Answer 2

5 units

Explanation:

Lets keep the missing side as x

And we also know that the area of Triangle is,

`(1)/(2) bh`

So taking this into consideration we can write a linear equation like this,

`(1)/(2) bh = 20`

Where height is 8,

`(1)/(2) * b * 8 = 20 \\ 4 * b = 20 \\ b = (20)/(4) \\ b = 5`

So therefore the missing side is 5
