What is 78,600 round to the nearest thousand

79,000 is the answer bc u look at the number on the right and if it is greater than 5 u add 1

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
