A hotel swimming pool is made up of four semicircles and a square. Find the perimeter of the swimming pool. Round your answer to the nearest tenth.

370.2

Step-by-step explanation:

We need to find the area of the square, and the area of the 4 semi circles and add them up.

The area of a square is given by the formula A = S², where the sides are 12. therefore:

12² = 144

4 semi circles are equivalent to 2 full circles. In order to find the area of the two circles, you can use the formula:

A = πr²   ⇒  where r is 1/2 the diameter

A = π(6)² ⇒36π *2(because its two circles)

Area of the 2 full circles it 72π ≅ 226.19

Then the area of the figure: 144+226.19

370.19 ≅ 370.2

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen
