Question

if a diagonal of rectangle is 26cm and one side is 24cm,find the other side​

Answer 1

let one side is x cm
we know that
diagonal² = length² +breadth²
26² = 24² + x²
676=576+x²
676-576= x²
100=x²
10 = x [because the length can not in negative ]
so length of another side is 10 cm

Answer 2

Answer:

by using pythagoras theoram we can find the answer  and i think that this will be helpful to everyone

Step-by-step explanation:

given,

the length of diagonal  =  26 cm

the length of first side  =   24 cm

the length of 2nd side  =   ?

therefore ;

ATQ;

pythagoras theoram = a^2 +b^2 = c^2

let a and b = sides ; c = diagonal

24^2 +b^2 =  26^2

576  + b^2 = 676

b^2 = 676 - 576

b     =  under root 100 = 10

therefore b = 10 cm
