Solution

The correct option is A

24.3m2


The area A of the rectangle with length l and width w is given by, A=l×w.

Step 1: Convert the dimensions into the meter.

l=5m40cm=5m40100m=5.4m:

w=4m50cm=4m50100m=4.5m

Step 2: Substitute l=5.4, w=4.5 into A=l×w and find the area of the room.

A=5.4×4.5=24.3m2

Hence, the correct option is a.
