84
2.1 * 40 = 84 p
0.2
2 m, 10 cm and 45 cm is an impossible triangle. Therefore there is no perimeter.
One tenth (1/10)
84
It is: 70cm+1m 40cm = 2m 10cm
2.1 * 40 = 84 p
As an improper fraction it is 3/2m
0.2
2 m, 10 cm and 45 cm is an impossible triangle. Therefore there is no perimeter.
One tenth (1/10)
It could be 2.75 metres.
10/100 which simplifies to 1/10
40 cm / 2m = 40 cm / 200 cm = 40/200 = 1/5
10cm = .1m or 1/10
10 cm is 1/10 of one meter.
