Math Grade 4 Quiz Area and Perimeter of Rectangles – 4.MD.A.3

This standard requires students to understand and apply formulas for finding the area and perimeter of rectangles in real-world and mathematical problems. For area, students use the formula Area = length × width, and for perimeter, they use the formula Perimeter = 2 × (length + width). They should be capable of manipulating these formulas to solve for unknown dimensions given other information, such as the area or perimeter and one of the dimensions.
