2)the scale of a map is 1cm to 5km .a farm is represented by a rectangle measuring 1.5 cm by 4cm. what is the actual area of the farm

• math -

5km=5000m = 500,000cm.

1. A = 5000 / 1000 = 5cm^2.

2. Am = 1.5 * 4 = 6cm^2 on map.

A = 500,000 * 5cm^2 = 2,500,000cm^2 =
Area of farm.

CORRECTION:
A = 500,000 * 6cm^2 = 3,000,000cm^2
