a) Perimeter of field on Map A = 7 + 5 + 7 + 5 = 24
Actual Perimeter of field
= 24 x 4000
= 96 000cm
= 960 m
b)
Map A
1cm: 4000cm
1cm^2 : 1.6 x 10^7cm^2
1.5 cm^2 : 2.4 x 10^7 cm^2
Map B
1cm : 2500cm
1cm^2 : 6.25 x 10^6 cm^2
Area of this garde, in cm^2, drawn on Map B
= (2.4 x 10^7 )/(6.25 x 10^6)
=3.84 cm^2
