Question

the sides of a rectangle are 12 m and 5 m what is the length of diagonal

Answer 1

the angles of a rectangle are right angles
then diagnol = root of 12square + 5 square
= root of 144+25
=root of 169
= 13

Answer 2

given :-

Length of the rectangle = 12m

breadth of the rectangle = 5m

we know that each corner of a rectangle forms a right angle.

therefore by Pythagoras theorem, we get :-


==> diagonal = √(length² + breadth²)

==> diagonal = √(12² + 5²)

==> diagonal = √(144 + 25)

==> diagonal = √169

==> diagonal = 13

hence, the Length of the diagonal of the rectangle is 13m.
