Question

What is the perimeter of this rectangle?

Answer 1

6
`√(17)` or 24.738634

Explanation:

We can use the Pythagorean theorem to find the length of the sides. We will only need to find the length of AB and AD, as AB = DC and AD = BC.

The picture shows the Pythagorean theorem being used to find AB and AD.

AB =
`√(17)`

AD =
`√(68)`

Now we can find the perimeter

2(
`√(17)`) + 2(
`√(68)`) = 6
`√(17)`
