In the original rectangle, the length is 20 inches and the width is 12 inches.
To find the new length in Spencer's smaller scale drawing, we need to calculate the new length based on the ratio of the original width to the new width.
The ratio of the original width to the new width is 12 inches : 1.5 inches = 8 : 1
Therefore, the new length in Spencer's smaller scale drawing would be 20 inches / 8 = 2.5 inches.
So, the length of the rectangle in Spencer's new scale drawing would be 2.5 inches.
