One side of a rectangular rug is 2.3m, and the other is 54cm shorter. Find the perimeter of the rug in meters.

We know the length of the carpet. By the condition of the problem, it is equal to 2.3 m.

Now we need to know the width of the carpet. Since it is said that the other side is shorter by 54 cm, then first we express 54 cm in meters and get 0.54 m.

Then subtract 0.54 m from 2.3 m, and we get the width of the carpet equal to 1.76 m.

According to the rule of finding the perimeter of a rectangle, add the length and width of the carpet, and multiply the resulting sum by 2.

(2.3 m + 1.76 m) * 2 = 8, 12 (m).

Answer: 8.12 meters – the perimeter of the carpet is rectangular.
