Final answer:
The area of the first rectangle is found by multiplying the length (4.5m) and the breadth (7.2m) which gives 32.4 m². In the second case, the area is calculated by multiplying the length (7.2m) and the breadth (0.25m) which gives 1.8 m².
Step-by-step explanation:
The area of a rectangle is calculated by multiplying the length and the breadth of the rectangle. Therefore, if the length = 4.5m and the breadth =720 cm (which is equivalent to 7.2 m), we can calculate the area in square metres by multiplying 4.5 m * 7.2 m = 32.4 m². For the second rectangle, the length = 720 cm or equivalent 7.2m, and the breadth = 25 cm or equivalent 0.25 m. The area of this rectangle is calculated by multiplying 7.2 m * 0.25 m which equals 1.8 m².
