Question

How do you find the diagonal of a rectangle whose sides measure 5 yd and 12 yd?

Answer 1

13 yd

Explanation:

Rectangles have 90 degree angles, so you use the Pythagorean Theorem `c^2 = a^2 + b^2`
The diagonal is the c side. So
`c^2 = 5^2 + 12^2`

`c^2 = 25 + 144 = 169`

`sqrt(c^2)= 13`
