Given:

A hotel swimming pool is made up of four semicircles and a square.

We need to determine the perimeter of the swimming pool.

Perimeter of the semicircle:

The perimeter of the semicircle can be determined using the formula,

$P=(\pi d)/(2)$

The diameter of the semicircle is 12 yd.

Substituting, we get;

p=((3.14)(12))/(2)

$p=18.84 \ yds$

Thus, the perimeter of the semicircle is 18.84 yards.

Perimeter of the swimming pool:

The swimming pool consists of 4 semicircles.

Thus, we have;

Perimeter=4(18.84)

$Perimeter=75.36 \ yards$

Rounding off to the nearest tenth, we get;

$Perimeter = 75.4 \ yards$

Therefore, the perimeter of the swimming pool is about 75.4 yards.
