## What is the formula for perimeter?

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. |

## How do you find the perimeter with the area?

**Perimeter** of a Rectangle

- Remember the
**formula**for**perimeter**and**area**of a rectangle. The**area**of a rectangle is a = length * width, while the**perimeter**is p = (2 * length) + (2 * width) - Substitute the known values into the
**area formula**. 36 = 4 * w. - Substitute values for length and width into the
**perimeter formula**.

## What is a perimeter of a shape?

The **perimeter of a shape** is the total distance around its edge. To calculate the **perimeter of a shape**, you just have to add up the lengths of all of its sides.

## What is a perimeter in math?

**Perimeter** is the distance around the edge of a shape. Learn how to find the **perimeter** by adding up the side lengths of various shapes.

## How do we calculate area?

For a square or rectangular room, you will first need to measure the length and then the width of the room. Then multiply the length and width. Length x Width = **Area**. So, if your room measures 11 feet wide x 15 feet long, your total **area** will be 165 square feet.

## What are the formulas for perimeter and area?

---|---|---|

Triangle | a + b + c | a, b and c being the side lengths |

Rectangle | 2(Length + Width) | |

Square | 4a | a =Length of a side |

Trapezoid | a +b+c+d | a, b, c, d being the sides of the trapezoid |

## How you find the perimeter of a rectangle?

The **perimeter of a rectangle** is the total length of all the sides of the **rectangle**. Hence, **we** can **find the perimeter** by adding all four sides of a **rectangle**. **Perimeter** of the given **rectangle** is a + b + a + b.

## What is the perimeter of shape B?

Answer: The **perimeter** of a two-dimensional **shape** is the distance around the **shape**. It is found by adding up all the sides (as long as they are all the same unit). The area of a two-dimensional **shape** is found by counting the number of squares that cover the **shape**.
