Question

On a map of scale 1:20,000 the area of a lake is 16cm2.What is the area of the real lake in m2?

Answer 1

Answer:

640000 m²

Step-by-step explanation:

Area of lake in map = 16 cm²

Side of lake in map = ✓16 cm = 4 cm

Therefore, real side of lake = (4 × 20000) cm = 80000 cm = 800 m

Hence, real area of lake = (800 m)² = 640000 m²
