Area and Perimeter of Rectilinear Shapes

Having built a foundation of  understanding with  "Finding the Area and Perimeter of Rectangles " the next step is to look at how to calculate the total area or perimeter of a shape made up of two or three non overlapping rectangles.  This set of differentiated worksheets provides a comprehensive way for students to work on this and apply the knowledge they have learnt previously.  The worksheets are organized into various sets, each with a specific focus and level of difficulty.

Set 1 focuses on the area of two non-overlapping colored rectangles laid out on a grid.

Set 2: Two non-overlapping rectangles

Set 2a: Area of two non-overlapping rectangles on a grid, where students must divide the shapes into individual rectangles.

Set 2b: Perimeter of two non-overlapping rectangles on a grid.

Set 2c: A combination of Sets 2a and 2b, covering both area and perimeter. 

Set 3 challenges students with rectangles that have rectangular holes, requiring them to calculate the area. 

Sets 4 Each shape has one or more unknown lengths that students must find first before calculating the area and perimeter. There is no background grid, so where the area calculation is concerned the area formula must be used.

Sets 5 and 6 introduce more complex shapes, now with three non-overlapping rectangles, firstly on a grid with set 5,  and then with measurements and no grid for set 6 where again students must find the 

missing lengths first.

Units of measurement
On the Sets of worksheets without grids you can choose to work with metric units (millimetres, centimeters and metres) or the U.S. customary measurement system inches, feet or yards. 

A standout feature is the worksheet randomization. With a single click, educators can generate an entirely new set of questions, making it a renewable resource for the entire school year. Be it for classwork, revision, or homework, the adaptability ensures students achieve proficiency in the topic.

Each worksheet concludes with an automatically generated answer key on its second page, offering a quick reference point for educators. And if there's ever a need for a last-minute lesson or work for a substitute teacher, these sheets are a reliable fallback.

Lastly, it's essential to note that these resources are compatible PDF documents. They operate seamlessly with the official Adobe Acrobat Reader on both Windows and Mac.
