Understand the Properties of Shapes, Including Perimeter and Area

Shapes come in all sizes and forms, and understanding their properties helps us in many real-world situations. Two important properties of shapes are their **perimeter** and **area**.

Perimeter:

The perimeter is the total distance around the edge of a shape. To calculate the perimeter, simply add up the lengths of all the sides of the shape. For example:

• For a rectangle, the perimeter is calculated by adding the lengths of all four sides: P = 2 × (Length + Width).
• For a square, the perimeter is calculated by adding the lengths of all four equal sides: P = 4 × Side.

Area:

The area is the amount of space inside a shape. It helps us determine how much surface the shape covers. To calculate the area, use the following formulas:

• For a rectangle, the area is calculated by multiplying the length and width: A = Length × Width.
• For a square, the area is calculated by squaring the length of one side: A = Side × Side.
• For a triangle, the area is calculated by multiplying the base and height, then dividing by 2: A = (Base × Height) / 2.

Examples:

1. A rectangle has a length of 5 cm and a width of 3 cm. The perimeter is 2 × (5 + 3) = 16 cm, and the area is 5 × 3 = 15 cm².

2. A square has a side length of 4 cm. The perimeter is 4 × 4 = 16 cm, and the area is 4 × 4 = 16 cm².

3. A triangle has a base of 6 cm and a height of 4 cm. The area is (6 × 4) / 2 = 12 cm².

Now, let's test your understanding of the properties of shapes, including perimeter and area!
