# Area of Plan Shapes

This tutorial will introduce you to PHP, a server-side scripting language you can use to make dynamic websites and web applications.

In this lesson, you will learn about the concept of area and how to calculate the area of different plane shapes. The area is the measure of the amount of space inside a two-dimensional shape. We will explore various plane shapes such as rectangles, triangles, circles, and parallelograms, and learn how to calculate their area using different formulas.

First, we will start with the most basic shape – the rectangle. We will learn how to find the area of a rectangle by multiplying its length and width. Then, we will move on to triangles and see how we can use half of the product of the base and height to calculate their area.

Next, we will explore circles and learn how to calculate their area using the formula A = πr^2, where A is the area, and r is the radius of the circle. We will also learn about the value of pi and its significance in calculating the area of circles.

Finally, we will look at parallelograms, and how to find their area using the formula A = base × height. We will also learn about the special case of a square, which is a type of rectangle with all sides equal.

By the end of this lesson, you will have a solid understanding of the concept of area and how to calculate the area of different plane shapes. You will also have gained confidence in your ability to solve problems related to calculating area.
