Answer:

100 m²

Step-by-step explanation:

The scale drawing has dimensions 25 cm and 16 cm

The actual rectangles dimensions are 50 times greater, that is

length = 25 × 50 = 1250 cm ← divide by 100 to convert to m

length = 1250 ÷ 100 = 12.5 m

width = 16 × 50 = 800 cm

width = 800 ÷ 100 = 8 m

Actual area = 12.5 × 8 = 100 m²
