Question

The sides of a rectangle are 6 cm and 8 cm respectively,
Find the length of the diagonal.​

Answer 1

Explanation:

As all the angles of the rectangle are 90 °

Applying Pythagoras Theorem on 2 adjacent Sides

We get Length of the Diagonal will be

√6²+8²=√100cm

Answer 2

Answer:

Given, sides of a rectangle are 6cm and 8cm

LET, ABCD be the rectangle

and BD is the diagonal

From ,triangle BCD we have

BC=8cm DC=6cm

By Pythagoras theorem,

BD^=BC^+DC^

=BD^=8^+6^

=BD^=64+36

=BD=√100

=BD=10

so, length of diagonal is 10cm
