Question

Write the Equations for the following statements :

(a) the perimeter of a triangle is 14 cm . the second side is 5 cm less than the first side and the third side is 3 cm more than the second side .
​​​

Answer 1

Step-by-step explanation:

let the first side be x

than the second side is x-5

and third side is 3+x-5

x+x-5+3+x-5=14

3x-7=14

3x=14+7

3x=21

x=21/3=7

first side =7 so second side =x-5

7-5=2

third side =3+x-5

3+7-5=5

7+5+2=14
