Question

How to find the length of a diagonal of a rectangle?

Answer 1

I'd suggest that you actually draw a rectangle and inside it draw a diagonal. What shape is formed by the diagonal and the two legs (made up by the length and width of the rectangle)?

Answer 2

It forms two right triangles

Answer 3

So how would I go about finding the length without an equation?

Answer 4

you use the pythagorean theorem.... \[a ^{2}+b ^{2}= c ^{2}\]

Answer 5

since no numeric values are given for the lengths, just solve the Pythagorean Theorem equation given you by RAM231 for D, the length of the diagonal.

Answer 6

Ok thanks!

Answer 7

You're welcome.

Answer 8

Your welcome for giving the equation :D I feel special now (:
