About this worksheet

Rectangles and squares with labeled sides to find the area. More uses sides up to 30.

What kids practice

Perimeter is the distance around a shape, and area is the space inside it. Fourth graders use formulas for rectangles. Perimeter is P = 2 × l + 2 × w, or 4 × s for a square. Area is A = l × w, measured in square units. They also work backward to find a missing side, like a rug with an area of 48 square feet and a width of 6 feet, which is 8 feet long.

Watch for

  • Mixing up area and perimeter, especially in word problems.
  • Adding only two sides for perimeter, like 8 + 5 = 13 instead of 26.
  • Writing perimeter in square units or area in plain units.
  • Dividing the perimeter by 4 to find the length of a rectangle that is not a square.

It's free to print, with Fewer, Standard or More on the page and an answer key. See the full area and perimeter guide for 4th grade.
