Lesson 2: Working out the Area of Quadrilaterals

Brain Teaser!

To get your brains thinking about Area, we would like you to try and draw 5 different shapes, each with an area of 25 square centimetres.

Below is an example: 


We have also included some printable squared paper if you wish to print it to help you. Otherwise you can draw little squares or draw a rough estimate of the shape.

Yesterday, we looked at working out the area of shapes by counting the number of squares inside the shape.

For example:


  To work out the area of this rectangle, I need to count how many squares are inside the shape.

I count 18 squares. So the area of this rectangle is 18 square centimetres.


Today we will be looking at working out the area of quadrilaterals using a few simple steps!


1. We need to look at what the length and width of our quadrilateral is first!



2. We need to multiply the Length and Width together!


  The length of this rectangle is 8cm and the width is 3cm.


Now let's multiply them together... 8 x 3 = 24!


3. Now include your units!

We always measure area using square centimetres or square metres.

The rectangle above is in centimetres.

So our answer will be 24 square centimetres!

Now this method of working out area requires you to know your times tables! cool

Times tables always creep up in lots of areas of Maths so it's very important to learn and memorise them. Not only is it a great skill to have but also makes Maths SO MUCH EASIER!


But for those of you who are still working towards memorising your timestables, we have included a times table square to help you with today's activity! There is also a printable one below.
