Question

A scale of 1 cm to 8 km is used for a map.

(i) If a forest has an area of 5 cm² on the map, find its actual area.
(ii)
If the actual area of a park is 128 km², calculate its area on the map.​

Answer 1

40 km^2

16 cm^2

Explanation:

A scale drawing is a reduced form in terms of dimensions of an original image / building / object

the scale drawing is usually reduced at a constant dimension

scale of the drawing = original dimensions / dimensions of the scale drawing

Actual area = scale factor x scaled area

8 x 5 = 40 km^2

Scaled area on the map = 128.8 = 16 cm^2
