Question

the perimeter of triangle is 49 CM one side is 7 cm longer than another side and 5cm shorter them the third side find the sides jaldi batao bhen aur bhai​

Answer 1

Step-by-step explanation:

hey your answer,

let one side be x

another side=x-7

third side=x+5

x+x-7+x+5=49

3x=51

x=17

so sides are=17,10,22✌✌☺☺

Answer 2

Answer:

Let the third side be  x.

Then Perimeter of triangle = Sum of all sides

⇒                  49cm                =  x - 7cm + x + 5cm + x

⇒                  49cm                =  2cm + 3x

⇒            49cm  -  2cm        =  3x  

⇒                  51cm                 =  3x

⇒            51 cm / 3                =    x

⇒                x                          =   17 cm

So, First side =  x = 17cm

      Second side = x - 7  = 17 - 7 = 10cm

      Third Side  =  x + 5 =  17 + 5 = 22cm
