To find the length of the rectangle in the new scale drawing, we need to maintain the original ratio between the width and length of the rectangle.
Given:
Original width = 12 inches
Original length = 20 inches
New width = 1.5 inches
The scale factor is calculated by dividing the new width by the original width:
Scale factor = 1.5 / 12 = 0.125
To find the length in the new scale drawing, we multiply the original length by the scale factor:
Length in new scale drawing = 20 * 0.125 = 2.5
Therefore, the length of the rectangle in Spencer's new scale drawing will be 2.5 inches.
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.
