Question

Find the length of diagonal of a rectangle whose dimension are 20m and 15m

Answer 1

As it is a rectangle, each angle will be 90°.

Let ABCD be the rectangle and BD be the diagonal.

AB=20m

AD=15m

By Pythagoras Theorem

AB²+AD²=BD²

20²+15²=BD²

400+225=BD²

BD²=625

BD=√625

BD=25

∴The length of the diagonal is 25 m.
