Geometry Practice Worksheets — Area, Perimeter & Volume
Geometry practice is best done with the formulas in front of you at first. These worksheets generate area and perimeter problems for rectangles, squares and triangles, and link directly to the UnitFig geometry formula sheet — print the sheet, work the problems, and check the key. Answers are given in square units so students get used to the units dimension.

Teaching tips for geometry practice
- •Area answers are in square units (sq units), perimeter answers are in plain units — the unit itself is half the lesson.
- •For triangles, the half matters: ½ × base × height. A triangle is half of a rectangle with the same base and height, which is why the ½ is there.
- •Use the formula sheet as a scaffold at first, then attempt problems without it as confidence grows.
Common mistakes to watch for
✗ Forgetting the ½ in triangle area.
✓ Remember: a triangle is half a rectangle. If the answer looks like it should be twice as big, you forgot the ½.
✗ Using perimeter formula for area (or vice versa).
✓ Perimeter is the distance around (add all sides, plain units). Area is the surface inside (multiply, square units). Say the word "around" vs "inside" before solving.

Frequently Asked Questions
What formulas are practiced?
Rectangle area (A = l × w), square area (A = s²), triangle area (A = ½ × b × h) and rectangle perimeter (P = 2(l + w)).
Where is the geometry formula sheet?
Visit the UnitFig formula sheet section — it lists every formula on these worksheets with worked examples and metric conversions.
What grade is geometry practice for?
Area and perimeter appear in grade 3–4 (3.MD.C.5, 4.MD.A.3) and the formulas are formalized in grades 5–8 (5.G.B, 8.G.C.9 for volume).
