Given: Height of the mast in a 28m long ship = 12m
To find: Height of the mast in a 9cm long ship
Substituting x1 = 28, y1 = 12, x2 = 9 in the formula,
Gives y2 = cm
= 3.85 cm
∴The height of the mast in a 9 cm long ship is 3.85 cm
Conclusion: Always maintain consistency in the units of x1 and y1, x2 and y2.
