Grade 7 | Unit 1 | Lesson 6: Scaling and Area | Practice Problems

On the grid, draw a scaled copy of Polygon Q using a scale factor of 2. Compare the perimeter and area of the new polygon to those of Q.

Diego drew a scaled version of a Polygon P and labeled it Q. If the area of Polygon P is 72 square units, what scale factor did Diego use to go from P to Q? Explain your reasoning.

Here is an unlabeled polygon, along with its scaled copies Polygons A–D. For each copy, determine the scale factor. Explain how you know.

An unlabeled four sided polygon with four different scale copies labeled A, B, C and D on a square grid. The unlabeled polygon has 4 sides, with a vertical height of 2 on the left side. The height of the vertical side in each polygon is as follows: Polygon A: 1 unit. Polygon B: 4 units. Polygon C: 3 units. Polygon D: 2 units.
