Question

The total length of the closed figure is called

• A. Area
• B. Perimeter
• C. Sum
• D. None of the options

Answer 1

The correct option is B

Perimeter

The correct option is (B)

The explanation of the correct option:

1. Perimeter is defined as the path or the boundary that surrounds the shape.
2. The unit of the perimeter is the same as the unit of length.
3. For example, a square has four sides. If one of its sides is 3cm long, the perimeter would be the sum of all its sides.
4. So, the perimeter of the given square will be 12cm.

The explanation of the incorrect option:

Option (A):

1. The area is defined as the space occupied by a flat shape or the surface of an object.
2. The unit of area is the square of the length of the side.

Option (C):

1. A sum is the result of an addition.
2. For example, adding 1, 2, 3, and 4 gives the sum 10, writing $1+2+3+4=10.$

Option (D):

1. The above-mentioned option does not match the required result

Thus, we observe that the total length of a closed figure is called the perimeter.
Hence, the correct answer is the perimeter, which is option (B).
