About This Worksheet

This easy-level worksheet contains 15 problems designed for 3rd Grade students practicing area and perimeter. Easy worksheets use simpler numbers and straightforward problem types to build confidence and reinforce foundational skills.

Working with rectilinear figures extends area and perimeter to irregular shapes, which are far more common in real life than simple rectangles. Students who can decompose complex shapes are developing the spatial reasoning needed for architecture and engineering.

  • Calculate area and perimeter of rectilinear (multi-rectangle) figures
  • Decompose a complex figure into simpler rectangles to find area
  • Distinguish between area (square units) and perimeter (linear units)
  • Find unknown side lengths in rectilinear figures using subtraction
  • Apply area and perimeter skills to real-world floor plan problems
