Given, the dimensions of 3 rooms
For each room, we will find the area which is the product of the dimensions
Room 1: 4.5 meters by 3 meters ⇒ Area of room 1 = 4.5x3 = 13.5 m²
Room2: 2 meters by 1.5 meters ⇒Area of room 2 = 2x1.5 = 3 m²
Romm3: 4 meters by 2 meters ⇒Area of room 3 = 4x2 = 8 m²
Total area = 13.5 + 3 + 8 = 24.5 m²
So, the answer is Total area = 24.5 m²
