Sarah is making a scale drawing of a painting that is 48 in. wide by 120 in tall. her paper is 12 in. wide and 24 in. tall. she decides to use the scale 1 in. = 4in. 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.
