  3. Check homework on angles Complete study guide and check.

  4. Check Study Guide

  5. Add these words to your vocabulary folder. We will be adding the formulas for area and perimeter.

  6. FORMULAS To KNOW!

  7. Draw and label each shape and write the formulas. See the example below. Side Side Use s for the length of each side when writing formulas.

  8. width length Use w for width and l for length when writing formulas.

  9. d height a c base Use a, b, c and d for the length of the sides.

  10. base 2 c height base 1 Use a, b1, c , and b2 for the length of the sides.

  11. a c height b Use a, b and c for the length of the sides and h for height.

  12. Diameter Use D for the diameter when writing the formulas.

  13. Square The square frame around the clock on Big Ben is a 7 meter square. What are the perimeter and area of the frame around the clock on the tower?

  14. Rectangle Central Park in New York City is 2.5 miles long and 0.5 miles wide. What are the perimeter and area of Central Park?

  15. Triangle The Louvre in Paris has a pyramid that serves as the main entrance. Each face of the pyramid is 35 meters long and has a height of about 27.03 meters. What is the are of each face?

  16. Parallelogram This building stands at the foot of Mt. Yatsugatake in Japan. It was designed to be an architect’s studio. If the base is about 6 meters long and 23.4 meters tall, what is the area of the face of the house facing you in this photograph?

  17. Rhombus The windows of the Swiss Re building in London are rhombi. Each side length of the rhombi are approximately 5.7 ft. long. Given this length, what would be the perimeter of each rhombus?

  18. Trapezoid Eye Bank is a medical facility in Venice, Italy. The trapezoid walls stand 12 meters high. The ground piece of the trapezoid is approximately 24 meters long and the top of the trapezoids are approximately 30 meters long. Given these dimensions, find the area of each trapezoid.
