## How do you find the area calculator?

**How to Find Area**

- Square Area Formula. A = a2 A = a × a.
- Rectangle Area Formula. A = l × w. l = length.
- Border Area Formula. A = (l1 × w1) – (l2 × l2)
- Trapezoid Area Formula. A = 1/2(a + b)h.
- Parallelogram Area Formula. A = b × h.
- Triangle Area Formula. s = 1/2(a + b + c)
- Circle Area Formula. A = πr2
- Ellipse Area Formula. A = πab.

## What is the area of quadrilateral?

To find the area of a rectangle, you need two measurements: the width, or base (the longer side of the rectangle), and the length, or height (the shorter side of the rectangle). Then, just multiply them together to get the area. In other words: Area = base × height, or A = b × h for short.

## What is the formula for total area?

Multiply the length of the base, b, by the height, h, to find the total area. The equation for the area, A, of a square or rectangle area can be written as: A = b * h. In our example, the base, b, is 12 inches, and the height, h, is 5 inches. Therefore, the area is 12 inches multiplied by 5 inches, or 60 square inches.

## What is the area and perimeter of all shapes?

Perimeter is the distance around a two-dimensional shape such as square or rectangle or triangle. Area : The amount of space inside the boundary of a two- dimensional shape such as a triangle or circle.
