The diagram shows a track composed of a rectangle with a semicircle on each end. The area of the rectangle is 7,200 square meters. What is the perimeter of the track? Use 3.14 for piπ. WILL MARK BRAINLIEST ! ⭐️

To solve this question, we need to know the formula for the perimeter of a semicircle and the area of a rectangle.

Area of a rectangle

Perimeter of a semicircle

Since we know that the width of the track is 120, and we are given the area, we can solve for the length of the rectangle by dividing the area by the width.

So the length is 60 meters.

However, this also happens to be the length of the diameter of the semicircle, which we can then plug in to the formula.

Then we will double this because there are two semicircles.

Now, we can add the outsides together to find the perimeter.

So the perimeter is 548.4 meters.

Hope this helped,
