Question

the length of the sides of a triangle are in the ratio 3:4:5. find the lengths of the sides of the triangle if its perimeter is 96cm

Answer 1

Answer:

let the angles be 3x,4x&5x

Now,

perimeter (p)=sum of all sides

or, 96=3x+4x+5x

or, 96=12x

or,96/12=x

or,8=x

or,x=8

Then,

3x=3*8

=24

4x=4*8

=32

5x=5*8

=45
