Penjelasan dengan langkah-langkah:

The pool has a length of 20 meters and a width of 10 meters, so the perimeter of the pool is:

P = 2(20m + 10m) = 60m

The path made of ceramics has a width of 1 meter, so the area of the path is:

A = 1m x 60m = 60m²

To calculate the total cost, we need to multiply the area of the path by the cost per square meter of ceramics:

Total cost = A x cost per m²

Total cost = 60m² x IDR 50,000/m²

Total cost = IDR 3,000,000

Therefore, the cost of making the path around the rectangular pool with a length of 20 meters and a width of 10 meters, with a 1-meter wide ceramics path, is IDR 3,000,000.
