Calculate the perimeter of a triangle in (cm) whose dimensions are 1m60cm,1m80cm and2m.
To calculate the perimeter, we need to add up the lengths of all three sides of the triangle:
1m60cm + 1m80cm + 2m
We need to convert all the measurements to the same units. Let's convert everything to centimeters:
160cm + 180cm + 200cm = 540cm
Therefore, the perimeter of the triangle is 540cm.
