A model ship is built to a scale of 1:400. If the actual length of the ship is 45 m, the length of the model will be cm. (DO NOT put CM in your
answer, only put an exact number without rounding) *

11.25

Step-by-step explanation:

Hero, we are interested in knowing the length of the model of the ship in cm

Now the ratio of the model to the actual is 1:400

let the length of the model be x

This means that;

1:400 = x: 45

1/400 = x/45

45 * 1 = 400 * x

x = 45/400

x = 0.1125

if we convert this to centimeters, we know that 100 cm equals 1 meter

so 0.1125 m will be 0.1125 * 100 = 11.25
