Find the perimeter of the figure. if you need to use pi in your computation, approximate its value as 3.14. rectangle topped by a semicircle a. 98.10 m b. 52.57 m c. 89.55 m d. 74.55 m

To solve this problem you must apply the proccedure shown below:
 As you can see in the figure attached above, the figure has a semicircle and a rectangle, then, you have that the perimeter is:
 P=(18x2)+15+(15/2)(3.14)
 P=36+15+23.55
 P=74.55
 Therefore, as you can see, the answer for this exercise is the last option, the option d, which is: d. 74.55
