What is the area and perimeter of all shapes?
Area and Perimeter Formula Chart
Figures | Area Formula | Variables |
---|---|---|
Area of Rectangle | Area = l × w | l = length w = width |
Area of Square | Area = a2 | a = sides of the square |
Area of a Triangle | Area = 1/2 b×h | b = base h = height |
Area of a Circle | Area = πr2 | r = radius of the circle |
What is the formula for perimeter of all shapes?
Perimeter, Area, and Volume
Table 1 . Perimeter Formulas | ||
---|---|---|
Shape | Formula | Variables |
Square | P=4s | s is the length of the side of the square. |
Rectangle | P=2L+2W | L and W are the lengths of the rectangle’s sides (length and width). |
Triangle | a+b+c | a,b , and c are the side lengths. |
What is the formula for finding area and perimeter?
Perimeter = a + b + c. There are several formulas for the area. If the base b and the corresponding height h are known, we use the formula. Area = (1 / 2) * b * h. If two sides and the angle between them are known, we use one of the formulas, depending on which side and which angle are known. Area = (1 / 2)* b * c sin A.
What is the formula for perimeter of a shape?
The basic formula is: P = 2 * (l + w). Perimeter is always the total distance around the outside edge of any shape, whether it is simple or compound. In this equation, P stands for “perimeter,” l refers to the length of the rectangle, and w refers to the width of the rectangle.
Is area and perimeter the same thing?
In geometry, area is the 2-dimensional space or region occupied by a closed figure, while perimeter is the distance around a closed figure i.e. the length of the boundary. For example, the area can be used to calculate the size of the carpet to cover the whole floor of a room. Perimeter can be used to calculate the length of fence required to surround a yard or garden.
What is the difference between area and perimeter?
Area vs. Perimeter. In geometry, area is the 2-dimensional space or region occupied by a closed figure, while perimeter is the distance around a closed figure i.e. the length of the boundary.
