The figure is made up of a semicircle and a triangle. Find the perimeter. Round your answer to the nearest hundredth

The perimeter of the figure is 86.53 meters

Step-by-step explanation:

we know that

The perimeter of the figure is equal to the circumference of a semicircle, plus the sum of the legs of the right triangle

step 1

Find the circumference of a semicircle

The circumference of a semicircle is given by the formula

we have

----> the radius is half the diameter

assume

substitute

step 2

The sum of the legs of the right triangle is equal to

step 3
