Area of a rectangle worksheets

Once a child has counted enough unit squares, the shortcut arrives: rows times columns. These free printable worksheets ask for the area of a labeled rectangle, which is the standard that turns counting into multiplying.

What's on this sheet

The region is shaded rather than outlined, and that is the one visual difference from the perimeter sheets. It is doing real work: perimeter is a question about the edge and area is a question about the inside, and the picture should not be silent about which one is being asked. A child who has both sheets in front of them can tell at a glance which is which.

Why this sheet works

The side lengths stay inside the times tables. A rectangle of 27 by 33 is a two-digit multiplication drill with a diagram on it, not an area question, so the levels here stop where the arithmetic would take over from the geometry.

How this one works

Area of a 7 by 6 rectangle

7 cm 6
  1. Both numbers you need are sides — no hunting for a height inside the shape, because the side IS the height here.
  2. So it is one times the other: 7 × 6 = 42 square cm. Nothing halves, nothing averages.
