Geometry and measurement challenge
4th Grade Math practice: A rectangular play space is 12 meters long and 7 meters wide. What is its area, and what is its perimeter. Part of year-end synthesis (Year-end Synthesis).
~11 min
Use shape attributes, perimeter, area, and angle reasoning together in one task.
Perimeter: Distance Around
8 (length)5 (width)
Perimeter = 2 × (8 + 5) = 26
Area = 8 × 5 = 40
The perimeter of a shape is the total distance around its outside edge, found by adding the lengths of all its sides together.
💡 Think of perimeter like building a fence around a yard.
