Question

If diagonal of a rectangle is 26 cm and one side is 24 cm, find the other side qqq

Answer 1

diagonal of rectangle = 26 cm

let the two sides of rectangle are( a, b).

let one side 'a = 24 cm'

since , we know that

diagonal of rectangle = √( a^2 + b^2 )

according to the given statement :
-------------------------------------------------
diagonal of rectangle = 26 cm

√ (a^2 + b^2 ) = 26

a^2 + b^2 = ( 26 )^2

( 24 )^2 + b^2 = 676

576 + b^2 = 676

b^2 = 100 => b = √100 = 10 cm

therefore,other side of rectangle =10cm

Answer : other side = 10 cm

Answer 2

If we cut a rectangle through its diagonal we get a right angle triangle...
That right triangle will have one side as
length of the one breath and diagonal as hypotence
Here we have one side as 24..
And hypotence as 26
So by applying Pythagoras thearm we get
A^2=B^2+C^2
C=(26*26_24*24)^1/2
=10
