Question

A tringular park has each side of length 425 m. Find it's perimeter and express it in km and m.

Answer 1

Answer:

425*3=1275 = 1.275km

Step-by-step explanation:

let a be the side of triangle.

Given , a=425

perimeter of equilateral triangle=3a

=3*a  =3* 425 = 1275 m

meter/1000=km

1275/1000=1.275 km

Answer 2

Step-by-step explanation:

length of each side = 425m

therefore,perimeter of triangle = (425×3)m=1275m

perimeter in km = (1275÷1000)km=1km 275 m
