Question

1
the number
as old as Garima. 10 years ago, Sudha was three times as old as12. The sides of a triangle are given by x, 2x + 2 and 3x – 2. If its perimeter is 30 cm,
then find the smallest side of the triangle.
18. Divide the share 100 between A and B such that twice of As share is less than
3 times of B's share by 200.​

Answer 1

Answer:

let the sides be ,

a=x

b=2x+2

c=3x-2

A.T.Q

a+b+c=30......(1)

therefore, putting value of a,b,c in eqn 1

x+2x+2+3x-2=30

6x=30

x=5

therefore,

a=x=5

b=2x+2=2*5+2=12

c=3x-2=3*5-2=13

therefore,a is the smallest side of the triangle.
