Question

on a certain map 2 cm represent one kilometre what area does 20 square centimetre on the map represent​

Answer 1

Answer:

5 square km

Step-by-step explanation:

since, 2 cm = 1 km

1 cm = 1/2 km

therefore,

x cm * y cm = 20 square cm

again

in kilometer,

(1/2)x * (1/2)y =(1/4)*x*y

=(20/4) { since X*Y=20 square cm}

=5 square km
