Break It Apart: Area of Combined Rectangles

Add up the areas in this engaging geometry worksheet! Young learners will explore how to find the area of combined rectangles by breaking them up into manageable sections. To do so, students will use strategies to calculate the area of each section, and then add the areas together to find the total.

Ideal for third- and fourth-grade students, this worksheet deepens understanding of area while reinforcing multiplication and spatial reasoning. Learners will build confidence decomposing shapes and using what they know about simpler figures to solve more complex problems.
