The length of the base of the plot is 12 feet, and the length of one side is 5 feet, as shown in the diagram. Tammy makes a scale drawing of the plot using a scale of 1 inch to 2 feet. The area of the plot in the scale drawing is square inches.

First, find the area of the plot.

Area = length x width

Area = 12 x 5

Area = 60 square feet.

The ratio of the scale to the plot is 1 inch : 2 feet

Square each of those:

1 square inch : 4 square feet

The plot is 60 square feet. 60 sq ft / 4 sq ft = 15

The area of the plot in the scale drawing is 15 square inches.
