Calculate the Area and Perimeter of Shapes

What are the formulas to calculate the area and perimeter of different shapes?

The formula to calculate the perimeter of a rectangle is: Perimeter = 2(length + width) The formula to calculate the area of a rectangle is: Area = length x width For a triangle, the formula to calculate the perimeter is by adding all three sides together, and the formula to calculate the area is: Area = 0.5 x base x height The formula to calculate the perimeter of a circle is: Perimeter = 2 x π x radius And the formula to calculate the area of a circle is: Area = π x (radius)² These formulas are essential in solving for the perimeter and area of different shapes.

Perimeter and Area Formulas

Perimeter: The perimeter of a shape is the total distance around its boundary. For rectangles, you can find the perimeter by adding twice the length and twice the width. Similarly, for triangles, the perimeter is the sum of all three sides. For circles, the perimeter is also known as the circumference and is calculated using the formula mentioned above.
Area: The area of a shape is the total amount of space enclosed by its boundaries. The area of a rectangle is calculated by multiplying the length by the width. In the case of triangles, the area is found by multiplying half of the base by the height. For circles, the area can be calculated using the formula mentioned above, where π is a mathematical constant approximately equal to 3.14159.
Understanding these formulas is crucial in solving various mathematical problems related to calculating the perimeter and area of shapes.
