a 10" by 11" transparency sheet is placed on an overhead projector. If the projector enlarges 300% what will be the lengths of the sides of the projection and how does the perimeter of the original transparency sheet compare to the perimeter of the projection?

Question

dumbcow · Answer

an increase of 300% is same as increase of 3 times the amount
10*3 = 30  ----> 10+30 = 40
11*3=33  ----> 11+33 = 44

The perimeter will enlarge at same rate of 300%
