Use what you know about decimals or fractions to explain why (0.2)⋅(0.002)=0.0004. A rectangular plot of land is 0.4 kilometer long and 0.07 kilometer wide. What is its area in square kilometers? Show your reasoning.

An area of rectangle: a · b

a = 0.4 km

b = 0.07 km

a · b = 0.4 km · 0.07 km = 0.028 km²

An area of rectangle: a · b

a = 0.4 km

b = 0.07 km

a · b = 0.4 km · 0.07 km = 0.028 km²

hi,

you half the rectangle that you ae asking about so then you would see the scale factor of 1/2 the one u have selected, the one on top is half.

hope this !
