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

$C=\pi r$

we have

$r=29/2=14.5\ m$ ----> the radius is half the diameter

assume

$\pi =3.14$

substitute

$C=(3.14)(14.5)=45.53\ m$

step 2

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

$20+21=41\ m$

step 3

Perimeter of the figure

$45.53+41=86.53\ m$
