Cover area and perimeter from concrete to abstract with nearly 30 free worksheets. Students begin determining area and perimeter with unit blocks, then calculate both for quadrilaterals, triangles, and circles, work backwards to find the length of a missing side, and solve area and perimeter word problems. Each worksheet is a printable PDF with a full answer key in multiple versions - no login or account needed - and most can be assigned online. Modified pages offer a lighter problem load, and the grading column with quick grade scale speeds up checking. These area and perimeter worksheets span 3rd through 7th grade geometry.
These worksheets cover a comprehensive range of quadrilateral measurement skills. Students find the area and perimeter of rectangles, explore rectilinear shapes by decomposing them into smaller rectangles, create rectangles with given area or perimeter constraints, and work with scale factors. Problem sets include whole numbers, decimals, and fractions, and span third through seventh grade standards.
Students practice finding a missing side length of a rectangle or right triangle when given the area or perimeter. These worksheets reinforce the relationship between side lengths, area, and perimeter through reverse calculation — dividing area by a known side or subtracting known sides from a total perimeter. Problem sets span third grade through middle school, with some including decimal values.
