What is perimeter formula?
The perimeter is the length of the outline of a shape.
To find the perimeter of a rectangle or square you have to add the lengths of all the four sides.
x is in this case the length of the rectangle while y is the width of the rectangle.
The perimeter, P, is: P=x+x+y+y..
What are the examples of irregular shapes?
Area Of Irregular Shapes – Definition with Examples Irregular shapes are the polygons with five or more sides of varying lengths. These shapes or figures can be decomposed further into triangles, squares, and quadrilaterals to evaluate the area.
How do you find the area and volume of a shape?
Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.
What is the formula of 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 I calculate the area of an irregular shape?
The simplest way to calculate the area of an irregular shape is to subdivide it into familiar shapes, calculate the area of the familiar shapes, then total those area calculations to get the area of the irregular shape they make up.

What is area and volume?
The area is the amount of space occupied by a two-dimensional flat object in a plane. Volume is defined as the space occupied by the three-dimensional object. It is always measured in square units. It is always measured in cubic units.

How do u find the mean?
How to Find the Mean. The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
