A high school track is shaped as a rectangle with a half circle on either side.

A rectangle has a length of 85 yards and width of 25 yards. 2 semicircles with diameters of 25 yards are on each end of the rectangle.

Jasmine plans on running three laps. How many yards will Jasmine run?

745.5

Step-by-step explanation:

To answer this question we need to find the perimeter and multiply it by three. To do that we can start by adding 85 yards plus 85 yards for both sides of the rectangle which equals 170. Then we need to add the circumference of the semicircles. To do that we can use the formula C = 2 (3.14) r. for that we need to find the radius which is the diameter divided by 2 which is 12.5. Then we can plug that into the formula to get C = (2) (3.14) (12.5). After solving that we get 78.5 which we can add to 170 to get the perimeter which is 248.5. However we are NOT done since jasmine is running 3 laps we need to multiply 248.5 by 3 to get an answer of 745.5.
