Title: Computing Perimeter of Square

Grade: 2-a Lesson: S1-L6

Explanation: The best way to understand geometry is by looking at some examples. Take turns and read each example for easy understanding.

Examples:

Find the perimeter of a square.

Step 1a

Given length of side(s) is 7 cm.

Perimeter of a square is \$4 \times s\$

Substitute the values \$4 \times 7\$ = 28 cm.

Therefore, the perimeter of a square is 28 cm.

$1a$

Explanation:

The length of one or more sides is 7 cm.

To find the perimeter of a square, multiply the length of one side by four \$4s\$.

Insert the length measurement on the side (4 multiplied by 7 equals 28 cm).

So, the perimeter of the square with a side length of 7 cm is 28 cm.

Step 1b

Find the side of a square whose perimeter of a square is 16 cm.

Given, Perimeter of a square is 16 cm.

Perimeter of a square = \$4 \times s\$

Substitute the values

16 = \$4 \times s\$

s = 4cm.

Explanation: The perimeter of a square is 16 cm.

For calculating the Perimeter of a square = \$4 \times s\$

After calculation, the side of each length is 4 cm.

Step 1c

The length of each side of the square is 4 cm.

Explanation: So, each side of the square is 4 cm in length.
