When you want to compare areas of different shapes, using formulas makes it a lot easier.
Each shape has its own way to calculate its area, like rectangles, triangles, and circles. Here are the formulas you need:
Rectangle: To find the area, you use this formula:
Area = length × width.
Triangle: For a triangle, the area can be found with this formula:
Area = ½ × base × height.
Circle: The area for a circle is calculated like this:
Area = π × radius² (where "radius" is how far it is from the center to the edge).
Once you know the areas, it's easy to compare them. Just plug in the numbers, do the math, and you can see which shape has a bigger area.
Let’s say you want to compare a rectangle that is 4 meters long and 5 meters wide with a triangle that has a base of 6 meters and a height of 3 meters. Here’s how you’d find their areas:
For the rectangle:
Area = 4 × 5 = 20 square meters.
For the triangle:
Area = ½ × 6 × 3 = 9 square meters.
Now, you can clearly see that the rectangle has a larger area!
It's all about breaking things down into simple steps.
