Question

Calculate the perimeter of a triangle in (cm) whose dimensions are 1m 60cm, 1m 80cm, and 2m
.

Answer 1

Answer:

540 cm

Step-by-step explanation:

1 m = 100 cm

1 m 60 cm = 100 + 60 = 160 cm

1 m 80 cm = 100 + 80 = 180 cm

2m = 200 cm

Perimeter of triangle = 160 + 180 + 200 = 540 cm

Answer 2

Answer:

Let the triangle be ABC

Step-by-step explanation:

AB=1m60cm=160cm (1m=100cm)

BC=1m80cm=180cm

CA=2m=200cm

Perimeter of triangle = sum of all sides

Perimeter od triangle ABC=AB+BC+CA

=160+180+200

Therefore perimeter of triangle ABC is 540 cm
