Question

Find the perimeter of a room which is 4.5 meters long and 3 meters wide.

a) 15 meters
b) 20 meters
c) 22.5 meters
d) 30 meters

Answer 1

The perimeter of the room is 15 meters.

Step-by-step explanation:

The formula to find the perimeter of a rectangle is P = 2L + 2W, where P is the perimeter, L is the length, and W is the width. Given that the length is 4.5 meters and the width is 3 meters, we can substitute these values into the formula to find the perimeter.

P = 2(4.5) + 2(3) = 9 + 6 = 15 meters.

Therefore, the correct option is a) 15 meters.
