Answer 1

Answer:

For knowing,how many rounds along the ground he travelled, we've to find the perimeter

and also mutliply by 3,as he completed 3 rounds.

That's

First let's find perimeter

we know

perimeter of a closed polygon= sum of all it's sides

here the same applies for a triangle

that is

Perimeter=25+18+17

Perimeter=60

therefore the perimeter is 60m

also he travelled 3 rounds, thus

60×3=180

therefore the man travelled a total of 180m along the ground while having 3 rounds
