Concept:To find the area covered by the map, convert the map's measured length and breadth into real ground distances using the scale, then multiply them.
Explanation:Use a ruler to measure the length of the map in centimetres.
Also measure the breadth of the map in centimetres.
Look at the scale given on the map.
If the scale says
1 cm=p km, multiply each measured distance by
p to get the true length and breadth in kilometres.
Let the true length be
L km and the true breadth be
B km.
Do not multiply centimetre readings directly, because that only gives the size on paper, not the real area.
Calculate the ground area using:
Area=L×B km2.Then round the result and choose the closest option.
Answer:The approximate area covered by the map is found by multiplying the converted length and breadth in kilometres.
