Question

find the perimeter of a square whose side is 2m 5dm

Answer 1

Length of a side of a square=2m 5dm=25dm
So, it's perimeter = (4 * 25) dm = 100 dm
Hence , the perimeter of the square is 100 dm.

Answer 2

The perimeter of the square will be 10 m

Given data :

Square's one side = 2m 5dm

= 2m + ( 5×0.1)m

= 2m + 0.5m

= 2.5 m

Perimeter = (4×one side) = (4×2.5)m = 10 m (answer)
