## What is the formula for finding area of a square?

Area of a square = side times side.

Since each side of a square is the same, it can simply be the length of one side squared.

If a square has one side of 4 inches, the area would be 4 inches times 4 inches, or 16 square inches.

(Square inches can also be written in2.)

## How do you calculate a square?

If you are measuring a square or rectangle area, multiply length times width; Length x Width = Area. For other area shapes, see formulas below to calculate Area (ft2) = Square Footage.

## 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 the area?

The most basic area formula is the formula for the area of a rectangle. Given a rectangle with length l and width w, the formula for the area is: A = lw (rectangle). That is, the area of the rectangle is the length multiplied by the width.

## 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.
