## What is the formula for 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.

## What is the area?

In geometry, the area can be defined as the space occupied by a flat shape or the surface of an object. The area of a figure is the number of unit squares that cover the surface of a closed figure. Area is measured in square units such as square centimteres, square feet, square inches, etc.

## 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 area of this trapezoid?

Explanation: To find the area of a trapezoid, multiply the sum of the bases (the parallel sides) by the height (the perpendicular distance between the bases), and then divide by 2.

## What does it mean to find the area?

Area is a measure of how much space there is on a flat surface. For example, in a rectangle we find the area by multiplying the length times the width. In the rectangle above, the area is 2×4 or 8. If you count the small squares you will find there are 8 of them.

## How do you explain area?

Area is the term used to define the amount of space taken up by a 2D shape or surface. We measure area in square units : cm² or m². Area is calculated by multiplying the length of a shape by its width.
