A rectangular field is 400 meters long and 350 meters wide. What is the area of the field in square kilometers?

0.14 km square

Step-by-step explanation:

Area = Length * Breadth (In rectangle)

=> So, as we have to find it in square kilometers, we can either first convert to km and then find the area, or first find the area and then convert.

Method 1: First convert : (Easier)

When we convert 400 meters to kilometers, we get,

1 meter = 0.001 kilometers

So, 400 meters = 0.4kilometers

And, 350 meters = 0.35 kilometers

Area = 0.4 * 0.35 = 0.14 square kilometers

Method 2 : First find :

400 meters * 350 meters = 140000 meters square

Note : Meters square = Square meters

=> 1 km square = 1000000 meters square

So, 140000/1000000

=> 0.14
