An object that is 90 in long is being drawn on two different blueprints. On blueprint A, a scale of 1in: 1ft is being used. On Blueprint B, a scale of 1in:30in is being used. what is the difference, in inches, between the lengths of the drawings

A scale is used to make a smaller replica of an object. You can find out the size of the smaller model by multiplying the original size with the scale ratio. One foot equal to 12 inches, so the scale for blueprint A is 1 in:12in. The length of the drawing of blueprint A will be 90 inches * 1 in/12 in= 7.5 in

On the other side, the blueprint B scale is 1 in:30 in, then the length of blueprint B will be: 90 inches* 1 in/ 30 in = 3 in

The difference in the length of the two drawings will be 7.5 in - 3 in = 4.5 in
