Find the perimeter of 54cm square rounding to the nearest tenth

Step-by-step explanation:

This problem is on the mensuration of flat shapes, a square.

we are given in this example that the side of the square is 54cm

now we know that the perimeter of a square is expressed as the summation of all its sides.

that is

perimeter = l+l+l+l

perimeter= 4l

substituting the value of l into the expression we have

perimeter= 4*54

perimeter= 216cm

From the analysis, the perimeter of the square shape was found to be 216cm

after simplifying it i got: -36.25 as my answer. hope that !

21/58.
