About this worksheet
The perimeter of a rectangle is the distance all the way around it, found by adding the four sides, or by doubling the length plus the width. On this fifth grade sheet a child sees twelve rectangles with the length and the width printed beside the sides and writes the perimeter in units.
It is a good moment to see why perimeter and area are different: one counts the edge, the other counts the squares inside. Each version has different rectangles, and the answer key gives every perimeter.
What your child will learn
- Add all four sides
- Use the shortcut 2 × (length + width)
- Write the answer in units
- Tell perimeter from area
Common Core standard: 4.MD.A.3
Worked example
A rectangle 7 units long and 4 units wide has perimeter 7 + 4 + 7 + 4 = 22 units.
Common mistake
Adding only two sides, or multiplying the sides, which gives the area.
Helpful hint
Perimeter = length + width + length + width. The answer is in units, not square units.
