ANSWER

66.3 m

Step-by-step explanation

We want to find the distance around the figure.

The figure is made up of a semi circle on a rectangle.

So, we have to find the perimeter of the semi circle (without adding the diameter) and the rectangle, but we will subtract 18 m from the perimeter of the rectangle since the person running does not run across that length.

The perimeter (circumference) of the semi-circle (without adding its diameter) is given as:

C = πr

where r = radius

The diameter of the semi-circle is 18 m, so its radius is:

r = D / 2 = 18 / 2

r = 9 m

So, the circumference is:

C = π * 9

C = 28.3 m

The perimeter of the rectangle is given as:

P = 2(L + B)

where L = length and B = breadth

So, the perimeter is:

P = 2(18 + 10) = 2 * 28

P = 56 m

Now, subtract 18 m:

P = 56 - 18

P = 38 m

Now, add the two of them:

P = 28.3 + 38

P = 66.3 m

So, if you run around the figure, you are traveling 66.3 m.
