Question

The sides of a triangle, taken in order, are each 3cm longer than the preceeding side. If the perimeter of the triangle is 81 cm. Find the sides of triangle

Answer 1

Answer:

the sides are 24 , 27 , 30

Step-by-step explanation:

let the shortest side be x .

each side increases by 3 . Therefore :

x+(x+3)+(x+3+3) = 81

3x+9=81

3x=81-9

3x=72

x=72/3

x=24

the sides are :

x , x+3 , x+6

24 , 24+3 , 24+6

24 , 27 , 30

Answer 2

Answer:

The side of triangle=27 cm
