Calculating areas could be a daunting task if the child is not equipped properly with the techniques on how to calculate and matters go more worse when there isn’t good practice. The children will calculate the area of different squares and rectangles. The basic formula for finding the area, in this case, is the length times the width. Also, they will learn how to find the area of a shape by counting squares. The method of questioning is also different as nowhere the questions give away straightforward the length and width of a shape. There is the picture showing the square or rectangle along with their dimensions.

How to find area of different shapes?

The area of a shape is the amount of space inside that shape. We can measure the area of a shape by counting how many squares of a certain size we can fit inside the shape. The unit we use to measure area can be square centimeters (cm²), square meters (m²), square feet (ft²), and so on. The area of different shapes can be calculated in different ways.

One of the simplest shapes to calculate the area of is a square. To find the area of a square, we just need to know the length of one of its sides. To find the area of a square with a side length of 4 cm, we would use the formula:

Area of square = side length × side length

So the area of our square would be 4 cm × 4 cm = 16 cm².

Another shape that we can easily calculate the area of is a rectangle. To find the area of a rectangle, we just need to know the length and the width of the rectangle. To find the area of a rectangle with a length of 6 cm and a width of 3 cm, we would use the formula:

Area of rectangle = length × width

So the area of our rectangle would be 6 cm × 3 cm = 18 cm²

A triangle is another shape that we can calculate the area for. In order to find the area of a triangle, we need to know its base and height. The base of a triangle is any one of the three sides of the triangle, and the height is a line drawn from a point on the base, perpendicular to the base. So, to find the area of a triangle with a base of 6 cm and a height of 4 cm we would use the formula:

Area of triangle = (base × height) / 2

So the area of our triangle would be (6 cm × 4 cm) / 2 = 12 cm²

A circle is a bit more complicated to calculate the area for, but it can be calculated using the formula :

Area of a circle = π × radius²

Where π (Pi) is a mathematical constant that is approximately equal to 3.14 and radius is the distance from the center of the circle to the edge. So if the radius of a circle is 3 cm the area of the circle would be:

Area of a circle = π × 3² cm² = 9π cm²

It is also worth mentioning that perimeter is the distance around the outside of a shape, it can be calculated using different formulas for different shapes. For example, the perimeter of a square is the sum of all four sides, so it is just 4 times the length of one side. While, the perimeter of a circle is called the circumference which can be calculated by 2 × π × radius

When it comes to more complex shapes, it’s often not possible to calculate the area by just using one formula. Instead, we may need to break the shape down into smaller shapes that we can calculate the area of and then add them together. This is called “composing” and “decomposing” shapes.

For example, let’s say we want to find the area of a irregular shape that is not easily measured by formulas, we can divide it into smaller shapes such as rectangles, triangles, and circles, then find the area of each small shape and add them together to get the area of the big shape.

It’s important to note that area and perimeter can be used in many real-life situations such as in construction, landscaping, and more, it’s a very valuable skill for kids to learn and can help them in many different fields.
