Hi ,
Given scale on a map is 1 : 20000
1 cm in map = 20000 cm original
Lake Area of in the map
= 1.6 cm²
= 1.6 × cm × cm
= 1.6 × 20000 cm × 20000 cm
= 1.6 × 2 × 2 × 10^8
= 6.4 × 10^8 cm²
Therefore ,
Actual area of the lake = 6.4 × 10^8
sq cm
I hope this helps you.

Answer:6.4×10∧8 OR 640000000
Step-by-step explanation:
1^2 : 1.6
20000^2 : ?
∴ ((20000^2 ×1.6) ÷1) = ? ( cross multiplication)
?= 6.4× 10^8
( the number of scale we squared as the unit of area is cm^2 or m^2; in the case of volume, the numbers would be cubed)
