To find the length of the rectangle in Spencer's new scale drawing, we can use proportions.
The original length of the rectangle is 20 inches and the original width is 12 inches. Let x be the length of the rectangle in Spencer's new scale drawing.
Thus, we can set up the proportion:
20 inches / 12 inches = x inches / 1.5 inches
Solving for x:
x = (20 inches * 1.5 inches) / 12 inches
x = 30 inches / 12 inches
x = 2.5 inches
Therefore, the length of the rectangle in Spencer's new scale drawing will be 2.5 inches.
20 in.
12 in.
