1.	1.A model of ship is made in a ratio 1 : 200.(i) If length of model is 4 cm then find the length of ship.(İİ) If area of deck is 1,60,000 sq.cm, then find the area of deck of model of theship.
Answer» Let length of model be xLet length of ship be 200x Now, length of model = 4 cmThen, length of ship = 2004 = 800 cm Area of deck of ship = 160000Let length of deck be ss^2 = 160000s = 400 cm Now, length of deck of model = 400/200 = 2 cmArea of deck of model= 22 = 4 cm^2

Answer»

Let length of model be xLet length of ship be 200x

Now, length of model = 4 cmThen, length of ship = 200*4 = 800 cm

Area of deck of ship = 160000Let length of deck be ss^2 = 160000s = 400 cm

Now, length of deck of model = 400/200 = 2 cmArea of deck of model= 2*2 = 4 cm^2
