Area of Rectangle Worksheets

On this webpage you will find our range of worksheets to help your child learn to work out the area of a range of rectangles.

These sheets are graded from easiest to hardest, and each sheet comes complete with answers.

Using these sheets will help your child to:

• understand what area is;
• know how to find the area of a rectangle by counting squares;
• know how to find the area of a rectangle by multiplying adjacent sides;
• find a missing side of a rectangle, when the area is known.
• find areas involving multiplying fractions;
• find areas of rectilinear shapes (shapes made up of rectangles)

• Area is the amount of space that is inside a shape.
• Because it is an amount of space, it has to be measured in squares.
• If the shape is measured in cm, then the area would be measured in square cm or cm²

Area of a Rectangle

• If you are measuring the area of a rectangle, then the area will equal the length multiplied by the width.
• Or Area of a rectangle = length x width.
• The area of the rectangle below is 5 x 3 = 15 squares.

A rectilinear shape is a shape made out of two or more rectangles.

You find the area by splitting the shape up into rectangles and then finding the area of each rectangle and adding them together.

Sheet 1 is a simple sheet that just involves counting squares (3rd grade)

Sheets 2 and 3 involve splitting the shapes into rectangles and finding the area of each one.

Sheets 4 and 5 are the same but use simple fractions and decimals.

This section contains worksheets on area at a 5th and 6th grade level.
