Question

The sides of a triangle are in the ratio 3:2:5 and its perimeter is 30cm. The length of the longest side is​

Answer 1

Answer:

Step-by-step explanation:

3x + 2x + 5x = 30

10x = 30

x = 3

We know longest side is hypotenuese...,SO i will have higher ratio

So 5 is the highest... 5x = 5*3 = 15cm

Answer 2

Answer:

LET THE NO. BE X = 3X,2X,5X

PERIMETER OF TRIANGLE = A+B+C

= 3X+2X+5X = 10X

= 10X=30

= X=3

=3X= 3*3=9

=2X=3*3=6

=5X=5*3=15

THEREFORE LENGTH OF LONGEST SIDE = 15 CM
