Question

Find the perimeter of a square with one
side :
(i)
12 cm
(ii) ​

Answer 1

Answer:

48 cm

Step-by-step explanation:

4×L≈Perimeter of square

Answer 2

Given:

✰ Length of one side of a square = 12 cm

To find:

✠ The perimeter of a square.

Solution:

Square:

A square is a rectangle with all its sides equal in length.

Here, we will calculate the perimeter of a square by using formula.

✭ Perimeter of square = 4a units ✭

Where,

• a is the length of one side of a square.

Putting the value of length of one side of a square in the formula, we have:

➤ Perimeter of square = 4 × 12

➤ Perimeter of square = 48 cm

∴ The perimeter of a square = 48 cm

What if we need to find area of square?

If we need to need area of square, we will use formula as given below,

✭ Area of a square = a² sq. units ✭

Where,

• a is the length of one side of a square.

Putting the values in the formula, we have:

➤ Area of a square = 12²

➤ Area of a square = 12 × 12

➤ Area of a square = 144 cm²

∴ The area of a square = 144 cm²
