This lesson contrasts area and perimeter and has varied exercises for students about both concepts.
This lesson presents the idea that the area of any right triangle is exactly half of a certain rectangle, and contains varied exercises for students.
This fifth-grade lesson explores the area of a rectangle with fractional side lengths. We tile the rectangle with unit rectangles and show that the area is the same as would be found by multiplying the side lengths. We multiply fractional side lengths to find areas of rectangles.
Brush up on your math skills relating to the area of rhombuses then try some practice problems to test your understanding.
