Quadrilaterals

All quadrilaterals have...

- 4 sides
- A pair of parallel lines
- All sides and angles equal to 360°
- Square and rectangle

What Are Quadrilaterals?

Every quadrilateral is simply a shape with four sides, but they all share some important features. You'll find that all quadrilaterals have exactly 4 sides and their internal angles always add up to 360°.

Most quadrilaterals contain parallel lines - these are lines that never meet, like railway tracks. Squares and rectangles are special types of quadrilaterals because they have 4 right angles (90° each).

Quick Check: Look around your classroom right now - can you spot at least three quadrilaterals? Your desk, the whiteboard, and even the windows are probably quadrilaterals!

These shapes aren't just for maths lessons - architects, designers, and engineers use quadrilaterals to create everything from buildings to video games.

Calculating Area - Example 1

Working out the area of rectangles and squares is straightforward once you know the magic formula. The formula is simply base × height (or length × width).

Let's tackle this step by step: if you have a rectangle that's 4cm wide and 10cm tall, you multiply 4 × 10 = 40. Therefore, the area is 40cm².

Top Tip: Always remember to include cm² (square centimetres) in your answer - it shows you're measuring area, not just length!

This formula works for any rectangle or square, making it one of the most useful maths skills you'll learn.

Calculating Area - Example 2

Here's another example to build your confidence with the base × height formula. When you see a rectangle measuring 7cm by 11cm, you simply multiply these numbers together.

Following our trusty formula: 7 × 11 = 77, which means the area is 77cm². Notice how the process stays exactly the same regardless of the numbers involved.

Remember: It doesn't matter which measurement you call the base and which you call the height - multiplication works the same way round!

Practice with different sized rectangles will make this calculation feel completely natural.

Calculating Area - Example 3

Let's try one more example to cement your understanding. This rectangle measures 12cm by 8cm, so we apply our reliable formula once again.

Using base × height: 12 × 8 = 96, giving us an area of 96cm². You're probably noticing how straightforward this becomes with practice.

Confidence Booster: You've now mastered the area formula for rectangles and squares - this skill will help you in geometry, design technology, and even real-life situations like measuring rooms!

The key is remembering that formula and always including the correct units in your final answer.
