Sarah is making a scale drawing of a painting that is 48 in. wide by 120 in. high. Her paper is 12 in. wide and 24 in. tall. She decides to use the scale 1 in. = 4 in. Is this a reasonable scale?

Given:

Painting's actual size: 48 in wide and 120 in high

Paper's actual size: 12 in wide and 24 in tall

Scale: 1 inch = 4 inches

48 in : 4 in = 12 inches

120 in : 4 in = 30 inches

The scale is not reasonable because the paper size is not sufficient for the painting.

Using the scale of 1 inch = 4 inches, the paper size needs to be 12 inches wide and 30 inches tall. The actual paper is only 24 inches tall.
