Find the perimeter. Use straight pi = 3.14.
Blank Space__________m
This is an illustration of a shape that is composed of a rectangle labeled five meters by seven meters and two semi-circles capping both ends labeled with a radius of two and five tenths meters.
Type the correct answer.
Hint: This is a rectangle and two halves of a circle.
To find the perimeter, we need to calculate the sum of the lengths of all the sides.
The length of the rectangle is 5 meters and its width is 7 meters. So, the sum of the lengths of the rectangle is 2 * (5 + 7) = 2 * 12 = 24 meters.
The semi-circles at each end have a radius of 2.5 meters each. The circumference of a semi-circle is half the circumference of a full circle, so the length of each semicircle is 0.5 * 2 * 3.14 * 2.5 = 7.85 meters. Since there are two semi-circles, the total length of the semicircles is 2 * 7.85 = 15.7 meters.
Therefore, the perimeter of the shape is 24 + 15.7 = 39.7 meters.
