Teaching tips and what to try next

Right for fourth graders who already find area and perimeter from a picture, as in Area of Rectangles on a Grid and Perimeter of Polygons. A quick sketch with the known sides labeled settles most confusion between the two ideas. For more multi-step reading of story problems, try Two-Step Word Problems.

10 versions, each with its own answer key

Same skill and layout, a fresh set of problems in every version, so children can keep practicing without repeating a page. Problems are not repeated between versions unless a skill has only a small number of possible problems (for example, the addition facts within 10).

About this worksheet

Fourth graders use the area and perimeter formulas for rectangles to solve real-world problems, and sometimes they must work backward to find a missing side. This fourth-grade worksheet gives eight word problems about familiar rectangles, such as a garden, a rug, a poster, and a playground.

Each page has two problems of each kind. Two ask for the area, and two ask for the perimeter, given the length and the width. The other four work backward: two give the area and the width and ask for the length, and two give the perimeter and the width and ask for the length. Side lengths are whole numbers from 2 to 15, and the units include inches, feet, yards, and meters. The kinds are mixed on the page, so students must read each question carefully to decide what it asks. Each of the ten versions has new problems and its own answer key.

How to use it: encourage your student to sketch a quick rectangle for every problem and label the sides they know. Then ask, "Is this asking about the space inside, or the distance around?" Area problems answer in square units, and perimeter problems answer in plain units. For a missing side, area problems become division (48 ÷ 6 = 8), and perimeter problems take two steps: halve the perimeter, then subtract the width. Students can check by putting their answer back into the formula.

The answer key gives each answer with its unit. For picture-based practice, try our Area of Rectangles on a Grid worksheet and our Perimeter of Polygons worksheet.
