Question 1 of 2

A rectangle has vertices at (2, 1), (8, 1), (8, 5), and (2, 5) on a coordinate plane. What is its area in square units?

Question 2 of 2

A rectangle has vertices at (1, 2), (7, 2), (7, 5), and (1, 5) on the coordinate plane. What is the perimeter of this rectangle?

How this fits in

Area and perimeter on the coordinate plane is one skill in the Coordinate Geometry unit. Students read the unit lesson, then earn a bronze, silver, or gold medal on their last 10 answers. Medals never go down. A mastered unit comes back for review after 1, 3, 7, 16, and 35 days so it stays learned.
