Area Worksheet
Two A4 pages: area on a true-size centimeter grid, length times width, shapes split into rectangles, missing sides and an answer key.
Area
1 How big is the area?
1 square = 1 cm². How many rows? How many squares in a row?
× = cm²2 Work out the area.
a) 6 cm long, 7 cm wide
× = cm²b) 9 cm long, 4 cm wide
× = cm²c) 7 cm long, 3 cm wide
× = cm²d) 6 cm long, 4 cm wide
× = cm²3 Split and count.
How many squares does each shape have? Split it into rectangles.
4 Square and garden bed.
a) A square has sides of 5 cm. How many cm² is it?
b) A garden bed is 5 m long and 4 m wide. How many m² is it?
5 Think backwards.
a) A rectangle has 18 cm² and is 3 cm long. How wide is it (in cm)?
b) A rectangle has 32 cm² and is 8 cm long. How wide is it (in cm)?
★ Brain teaser
A rectangle is twice as long as it is wide. It is 5 cm wide. What is its area?
6 Draw two different rectangles of 12 cm² each. Write the calculation next to them.

What is on the worksheet?
The example at the top shows a rectangle as rows of square centimeters: 3 rows of 4 squares make 12 square centimeters. In task 1 your child counts rows and squares on the grid. Task 2 works out the area from length and width. Task 3 splits shapes into rectangles and counts. Task 4 has a square and a garden bed measured in square meters, and task 5 works backwards from the area to a missing side. A brain teaser and a grid for drawing two different rectangles with the same area finish page 1. Page 2 has all the answers.
Who is it for?
Grades 3 and 4, when area is introduced as the number of square units inside a shape.
How to use it
Count the squares one by one first. Then show how rows times squares per row gives the same number faster.
Frequently asked questions
Is there an answer key?
Yes. Page 2 shows every answer and a short note for parents and teachers. You can leave it out when you print.
Can I get new problems?
Yes. “New numbers” opens the worksheet generator with the same topic and new numbers, as often as you like.
Are the squares really one centimeter?
Yes, when you print on A4 paper at 100% scale. On US Letter with “Fit to page” the squares come out slightly smaller; the answers stay the same.
