Question

12. If diagonal of a rectangle is 26cm
and one side is 10cm, find the other
side.​

Answer 1

Step-by-step explanation:

By using Pythagoras theorem,

$26 {}^{2} - 10 {}^{2} = x {}^{2} \\ x {}^{2} = 676 - 100 \\ x {}^{2} = 576 \\ x = 24cm$

Answer 2

Answer:

Step-by-step explanation:

ABCD is a rectangle

B C= 10 cm

A C =26 cm

be use $H^{2} =B^{2} +P^{2} \\B^{2} =H^{2} - P^{2} \\B^{2} =(10)^{2} - 26^{2} \\ B^{2} =100-676\\B^{2} =576\\B=\sqrt{576} \\B=\sqrt{22*22} \\B=22$

so, AB =22 cm
