Question 1136819: In a scale drawing of a house, width, 150cm, of a door is represented by a line 30mm long. Find actual area land, in sq metres, occupied by house if corresponding area of plan is 3250cm². Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! 30mm:150cm
3 cm:150 cm
1:50 linear or 1:50^2 area or 1:2500
therefore 3250:(2500*3250) units cm^2
8125000 cm^2 or (divide by 10^2*10^2, or 10000)
812.5 m^2
