245 cm = 2.45 metres and 300 cm = 3 metres. 2.45 x 3 = 7.35 square metres.
1.6 square metres = 1.6 x 10000 square cm = 16000 square cm
If 23 of the area of the square is 54 then the area of the whole square is 54/23 = 2.3478 square metres. The sides are, therefore, 1.5323 metres and so the perimeter is 6.1290 metres.
8000 sq cm = 0.8 sq metres
It is 23 square metres.
245 cm = 2.45 metres and 300 cm = 3 metres. 2.45 x 3 = 7.35 square metres.
100 cm = 1 metre 230 cm = 2.3 metres 236 cm = 2.36 metres 2.3 x 2.36 = 5.428 square metres

1.6 square metres = 1.6 x 10000 square cm = 16000 square cm
15m square is equal to 2,250,000 cm square. Note though, that 15m square is not the same as 15 square metres.
100 x 100 = 10000 square cm for one square metre. So 70000 for 7 square metres.
If 23 of the area of the square is 54 then the area of the whole square is 54/23 = 2.3478 square metres. The sides are, therefore, 1.5323 metres and so the perimeter is 6.1290 metres.
8000 sq cm = 0.8 sq metres
8 square metres = 80 000 square centimetres (because a rectangle 8 m × 1 m would be 800 cm × 100 cm). 20 cm × 20 cm = 400 cm2. 80 000 / 400 = 200 tiles.
It is 23 square metres.
10-4 square metres.
100 x 100 = 10000 square cm for one square metre. So 70000 for 7 square metres.
