Question

The sides of a triangle are in the ratio of 3:4:5 and it’s perimeter is 510m. What is the measure of its greatest side?

Answer 1

Answer:

As 3:4:5 is the ratio,

3x+4x+5X=510

12x=510

x=510/12

x=42.5

3x= 127.5 m

4x= 170 m

5x= 212.5 m

therefore , 212.5m is the answer

Answer 2

Answer:

212.5m

Step-by-step explanation:

Given -

perimeter = 510m

Ratio of sides = 3:4:5

Sol -

Let x be constant of proportionality

Perimeter = 3x + 4x + 5x

510 = 12x

x = 42.5m

Biggest side is 5x

i.e. 5*42.5

Biggest side is 212.5m
