A model of a ship is made to a scale of 1:500. Find: The area other deck o the ship, if the area of the deck of its model is m2
उत्तर
Scale = 1:500
`"Area(deckmodel)"/"Area(decckship)"` = Scale
`(1.6 xx 100 x 100)/("Area(deckship)" xx 100 xx (1000)^2) = (1)/(500)^2`
Area(deckship) = `(1.6 xx 2500)/(10000)`
Area(deckship) = 0.4km2.
