## What is the difference between perimeter and area with examples?

Area- Area is defined as space/region occupied by a two-dimensional flat object. It is measured in square units. Perimeter- Perimeter is defined as the length of boundaries of a closed figure. For example, a square having side length equal to ‘a,’ then the perimeter will be the sum of all its four sides, i.e. ‘4a.

How do you find perimeter and surface area?

Divide the perimeter by 4: that gives you the length of one side. Then square that length: that gives you the area. In this example, 14 ÷ 4 = 3.5. (3.5)² = 12.25 square feet.

Is area and perimeter the same for rectangle?

The area of a rectangle depends on its sides. Basically, the formula for area is equal to the product of length and breadth of the rectangle. Whereas when we speak about the perimeter of a rectangle, it is equal to the sum of all its four sides.

### Is surface area equal to perimeter?

No. For example the surface area or area of a circle or radius r is pir^2 while the perimeter or circumference is 2pir. They are equal only when r = 0 or pir =2, that is r = 2/pi.

Can two different shapes have the same area and perimeter?

Recognize that shapes with the same areas can have different perimeters and vice versa. Likewise, it is not always true that shapes with the same perimeter have equal area. Now try a few practice questions!

What shape has same area and perimeter?

A two-dimensional equable shape (or perfect shape) is one whose area is numerically equal to its perimeter. For example, a right angled triangle with sides 5, 12 and 13 has area and perimeter both have a unitless numerical value of 30.

## How is surface area different from area?

The main difference between area and surface area is that area is used to describe the space occupied by a two-dimensional shape, whereas, surface area is the area occupied by the outer surface of a three-dimensional shape.

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.

### 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?

The perimeter is the sum of all sides of a figure to get one length. So, to find the perimeter, the formula is base + height + base + height.
