Spencer draws a rectangle to represent the size of the city block where he lives. The rectangle is labeled in inches. Spencer decides he wants to make a smaller scale drawing of the rectangle in which the width is just 1.5 inches long. What will be the length of the rectangle in Spencer's new scale drawing? Write your answer in decimal form.

Question

Left side of the rectangle is 12 inches and on the top of the rectangle is 20 inches

Answer 1

Since Spencer's new scale drawing has a width of 1.5 inches, we need to find the length in this new scale.

The original width is 12 inches and the original length is 20 inches.

To find the new length in Spencer's scale drawing, we can set up a proportion:

12 inches = 1.5 inches
20 inches = x

Cross multiplying, we get:

12 * x = 1.5 * 20
12x = 30
x = 30 / 12
x = 2.5

Therefore, the length of the rectangle in Spencer's new scale drawing will be 2.5 inches.
