A kite has a perimeter of 72cm. the ratio isit short size to it long size is 1:5. 1.find the area
2.find the perimeter if the ratio is 1:7.
3 it new area

area= 180cm²

Step-by-step explanation:

1+5+1+5= 72cm

ratio12= 72cm

find 1

1×72÷12= 6cm (as the shorter size)

5×72÷12= 30cm (longer size)

area= L×w

30×6= 180cm²

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.
