Answer:

1250 m^2

Step-by-step explanation:

The scale is 1 cm: 250 cm.

250/1 = 250

Each length in the pool is 250 time the corresponding length in the scale drawing.

Length = 20 cm

Real length = 250 * 20 cm = 5000 cm = 5000 cm * (1 m)/(100 cm) = 50 m

Width = 10 cm

Real length = 250 * 10 cm = 5000 cm = 2500 cm * (1 m)/(100 cm) = 25 m

area = length * width

area = 50 m * 25 m = 1250 m^2
