Increase the scale factor of the original shape's length and width to the desired scale. 5. Solve for the new scale drawing. 6. Check your work for reasonableness. Example Problem: Find the area of a rectangle with perimeters of 3 cm width and 4 cm length. Then, reproduce the rectangle at a scale factor of 4. What is the area of the new rectangle?... For this Think About It problem, pairs work together to solve the problem. Pairs will pretty quickly begin to create a ratio table or double number line, and will see that they will need to list many equivalent ratios to get to 36 pounds of rice.
