What is area Science?
Area (symbolized A ) is a two-dimensional quantity representing amount or extent of surface. The standard unit of area in the International System of Units ( SI ) is the meter squared (m 2 ). Area is usually measured or defined on a flat surface, also called a Euclidean plane, or on a spherical surface.

What is the perimeter of a polygon?
Briefly, for a polygon, the perimeter is the sum of the sides of the polygon. For example, for a square, the perimeter is the sum of its 4 sides; for a triangle, it is the sum of its 3 sides, and so on. The perimeters of the following figures are all determined by summing each side of the figure: Curved figures, such as circles, also have ...
How to measure the perimeter of a curved figure?
One way to measure the perimeter of curved figures in a real-world setting is to use some string or rope to form the outline of the shape then measure the length of string required to outline the shape. However, depending on the size of the figure, as well as other factors, this may not be possible.
How to find the area of a unit square?
The total area of a figure can be determined by counting the number of unit squares that fit within the figure; this can be exact depending on the figure, and if not, unit squares can still be used to approximate the area.
How many square units are in a rectangle?
In either case, their areas will be the same; the area of the rectangle is 12 square units; the area of the square is 9 square units, and the area of the triangle is 12.5 square units.
What is the area of a figure?
The area of a figure is a measurement of the amount of space the figure takes up. Another way to think of area is as the measure of the space enclosed by a figure. For example, the area of a square is made up of the space between each side of the square.
Do curved figures have perimeters?
Curved figures, such as circles, also have perimeters. In the case of a circle, the perimeter is instead referred to as the circumference of the circle. Calculating the perimeter of curved surfaces, particularly irregular ones, can be a lot more difficult than calculating the perimeter of shapes made up of line segments.
