Answer:
0.075 sq km
Step-by-step explanation:
Given that there is a rectangular field with dimensions of length =300 m and width = 250 m.
We have to calculate area of this rectangle in the units of square kilometres.
Let us convert length and width into km
1000m = 1 km
Hence length = 300/1000= 0.3 km and
width = 250/1000 = 0.25 km.
ARea = length x width = 0.3 x 0.25
=0.075 square km.
