Question

1. Find the length of the diagonal of a
rectangle whose breadth and length are
8 cm and 15 cm, respectively.​

Answer 1

Answer:

by Pythagoras theorem

Step-by-step explanation:

L = 15

B = 8

In ADC,

AD = 8 , DC = 15 AC = x ( diagonal )

${ad}^{2} + {dc}^{2} = {ac}^{2}$

${8 }^{2} + {15}^{2} = {ac}^{2}$

$64 + 225 = {ac}^{2}$

$289 = {ac}^{2}$

$\sqrt{289} = ac$

AC = 17

Diagonal = 17
