Question

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

Answer 1

Answer:

5 units

Step-by-step explanation:

Lets keep the missing side as x

And we also know that the area of Triangle is,

$\frac{1}{2} bh$

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

$\frac{1}{2} bh = 20$

Where height is 8,

$\frac{1}{2} \times b \times 8 = 20 \\ 4 \times b = 20 \\ b = \frac{20}{4} \\ b = 5$

So therefore the missing side is 5

Answer 2

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
