Which of the following gives the correct method for calculating the perimeter of a room measuring 5m by 6m?
Show workings
To calculate the perimeter of a room, you need to add up all the sides of the room. In this case, for a room measuring 5m by 6m, you have two sides measuring 5m and two sides measuring 6m.
So, the correct method for calculating the perimeter would be:
Perimeter = 2 * (length + width)
Let's plug in the values:
Perimeter = 2 * (5m + 6m)
Perimeter = 2 * (11m)
Perimeter = 22m
Therefore, the correct method for calculating the perimeter of a room measuring 5m by 6m is to multiply the sum of the length and the width by 2, which gives a result of 22 meters.
