Area, perimeter & volume worksheets

Measuring the space inside and around figures, from rectangles to prisms.

Area, perimeter & volume 12 skills

Area & perimeter Area is the space inside a shape. Perimeter is the distance around the outside. For rectangles, area = length × width and perimeter = 2 × (length + width).
Area of composite figures Split the figure into rectangles and triangles, then add their areas. For a cutout, subtract the missing area.
Area of parallelograms Area is base times height, and the height is the dashed line standing square on the base, not the slanted side.
Area of triangles A triangle is half its box: multiply base times height, then cut the answer in half.
Rectilinear area Split the shape into two rectangles and add their areas, or find the big rectangle and take the notch off.
Surface area using nets A net is a solid unfolded flat. Surface area is the area of every face added up, so find each face on the net and add.
Volume of rectangular prisms Volume is length times width times height. Count the cubes in one layer, then stack the layers.
Area by counting unit squares Count the unit squares to find each area. Include square units.
Surface area with nets Use each net to find the requested area or length. Show your work and include units.
Volume with unit cubes Each small cube represents one cubic unit. Find each volume.
Volume of composite figures Find each volume. Show your work and include cubic units.
Volume of composite figures Find each volume. Show your work and include cubic units.
