The perimeter of a square is defined as the total length of its boundary. Since a square has four equal sides, the perimeter is calculated by adding all four sides together. This measurement is expressed in linear units such as centimeters, meters, inches, or feet.

All sides of a square are equal in length, which means we can find the perimeter by simply multiplying the length of one side by 4. The formula for the perimeter of a square is P=4×side=4aP = 4 \times side = 4aP=4×side=4a, where 'a' represents the length of one side of the square.

Examples of Perimeter of a Square Calculations Example 1: Finding the Perimeter with a Known Side Length Problem:

What will be the perimeter of the square whose side is 101010 cm?

Step-by-step solution: Step 1, Look at what we know. The side of the square is 101010 cm. Step 2, Remember the formula for the perimeter of a square: P=4×sideP = 4 \times sideP=4×side Step 3, Put the side length into the formula: P=4×10=40P = 4 \times 10 = 40P=4×10=40 cm Step 4, The perimeter of the square with side 101010 cm is 404040 cm.

Example 2: Finding the Perimeter from the Area Problem:

If the area of the square is 144144144 m², what will be the perimeter?

Step-by-step solution: Step 1, We know the area of the square is 144144144 m². Step 2, To find the side length, we use the formula: side=areaside = \sqrt{area}side=area​ Step 3, Calculate the side length: side=144=12side = \sqrt{144} = 12side=144​=12 m Step 4, Now we can find the perimeter using: P=4×side=4×12=48P = 4 \times side = 4 \times 12 = 48P=4×side=4×12=48 m Step 5, The perimeter of the square is 484848 m.

Example 3: Finding the Side Length from the Perimeter Problem:

If the perimeter of a square is 565656 cm, what will be the side of the square?

Step-by-step solution: Step 1, We know the perimeter of the square is 565656 cm. Step 2, Remember that the perimeter equals 444 times the side length: P=4×sideP = 4 \times sideP=4×side Step 3, To find the side length, we rearrange the formula: side=P÷4side = P \div 4side=P÷4 Step 4, Put our value into the formula: side=56÷4=14side = 56 \div 4 = 14side=56÷4=14 cm Step 5, The side of the square with perimeter 565656 cm is 141414 cm.
