Final Answer:
The area of each irregular shape is found by breaking it into rectangles, measuring each rectangle’s length and width, multiplying them to get the area, and then adding all the areas together.

Explanation:
- First, look at the weird shape. It’s not a simple square or rectangle — it’s made of smaller rectangles stuck together.
- Imagine cutting the shape into separate rectangles. Each one should be easy to measure.
- For each rectangle, use a ruler (or pretend you have one) to measure how long and how wide it is.
- Multiply length × width for each rectangle — that gives you its area.
- Add up all the areas from each rectangle. That total is the area of the whole weird shape.
- Do this for every shape on the page. Write your answer in the “Area = ___” box.
Example:
If one rectangle is 3 cm long and 2 cm wide, its area is 3 × 2 = 6 cm².
If another rectangle next to it is 4 cm long and 1 cm wide, its area is 4 × 1 = 4 cm².
Total area = 6 + 4 = 10 cm².

Teach the Topic:
This is about finding the area of shapes that aren’t just squares or rectangles — we call them “irregular shapes.”
Think of it like a puzzle. Even if the shape looks complicated, you can break it into pieces that are easy to work with — like small rectangles.
You already know how to find the area of a rectangle: just multiply length × width.
So, you do that for each piece, then add them all up. That’s the total area!
Simple Example:
Imagine a shape that looks like an “L.” You can split it into two rectangles: one on top and one on the side.
Measure each, find their areas, and add them. Done!

Practice Task:
Draw an “L” shape using two rectangles: one 5 cm long and 2 cm wide, and another 3 cm long and 2 cm wide.
Find the total area of the whole “L” shape.
(Do NOT solve it — just try it yourself!)
