Question

the diagonal length of a rectangle whose sides are 4 cm and 3 cm is

Answer 1

4^2+3^2 =5^2
so diagonal is 5 cm

Answer 2

IN a rectangle, if sides are given and we need to find the diagonal we can use Pythagoras theorem to solve this.
=>H^2= B^2+ P^2
= (3)^2 + (4)^2
= 9+16
=25
H^2=25
=> H=5 cm
