2km=2 kilometer
kilo=1000 so 2 km=2000m
25m
2500cm
cm=centimeter=1/100 of a meter
so
2500cm=25m
mm=milimeter=1/1000 meter
so
3000mm=3m
so the longets is obviously 2000m or 2km
Answer: The answer is in the first image.
Explanation: The explanation is in the second image.
≠ means not equal to
L x w = 36
2L + 2w = 30
1. Find the multiples of 36
1 and 36
2 and 18
3 and 12
4 and 9
6 and 6
2. Figure out which set of numbers multiplied by 2 equals 30.
For 1 and 36:
2(1) + 2(36) = 2 + 72 = 74 ≠ 30
For 2 and 18:
2(2) + 2(18) = 4 + 32 = 36 <span>≠ 30
For 3 and 12:
2(3) + 2(12) = 6 + 24 = 30
So your answer is 3 and 12</span>
