Chapter 10.1-10.4 Review Understand how to use formulas to find area and perimeter
DO NOW: A particular rectangle has an area of 36 square feet and a perimeter of 26 feet. If the rectangle is scaled (dilated) by a factor of 3, what would be the perimeter and area of the resulting image?

Chapter 10.1-10.4 Review Understand how to use formulas to find area and perimeter
DO NOW: The wallpaper pattern shown is a rectangle with a base of 4 ft. and a height of 3 ft. Use the grid to find the area of the shaded kite. If the kite’s wall paper pattern costs \$24 per square foot to manufacture. How much will it cost just to create the kite? A = 3 ft2 \$72 per sq. ft.

Find the area of the regular polygon. 29. 27. 28.

30. The area of a regular nonagon is 34 m2. What is the area of a regular nonagon with sides five times the sides of the smaller nonagon? 31. The longer base of a right trapezoid is 12 ft. The longer base of a similar right trapezoid is 30 ft. The area of the smaller right trapezoid is 20 ft2. What is the area of the larger right trapezoid?

32. The longer base of a trapezoid is 8 ft. The longer base of a similar trapezoid is 13 ft. The area of the smaller trapezoid is 240 ft2. What is the area of the larger trapezoid? 33. Two similar parallelograms have areas 125 m2 and 80 m2. The height of the larger parallelogram is 10 m. What are the lengths of the bases of both parallelograms?

34. The longer sides of a parallelogram are 6 ft. The longer sides of a similar parallelogram are 15 ft. The area of the smaller parallelogram is 27 ft2. What is the area of the larger parallelogram? 35. Two similar parallelograms have areas 72 m2 and 32 m2. The height of the larger parallelogram is 12 m. What are the lengths of the bases of both parallelograms?

36. The shortest side of a pentagon is 4 cm. The shortest side of a similar pentagon is 9 cm. The area of the larger pentagon is 243 cm2. What is the area of the smaller pentagon? 37. How would increasing the length and width of a rectangle by a scale factor of 4 affect the area of the new figure? Explain.
