Answer:
1.62m^2
Step-by-step explanation:
From the problem statement, the scale of the drawing is
1cm:45cm (meaning that 1cm on the drawing represent 45cm in reality ofr actual)
first,let us convert 20cm to the actual drawing
20cm in actual will give 20*45=900cm
to meters =900/100= 0.9m
Secondly let us convert 40cm to the actual drawing
20cm in actual will give 40*45=1800cm
to meters =1800/1000= 1.8m
Now we can calculate the actual area in meters we have
area= 0.9*1.8
area= 1.62m^2
