Answer 2

Given:

Length (side) = 19 cm

What To Find:

We have to find the perimeter of the square.

Formula Needed:

Perimeter = 4 × side

Solution:

Using the formula,

⇒ Perimeter = 4 × side

Substitute the values,

⇒ Perimeter = 4 × 19

Multiply the values,

⇒ Perimeter = 76 cm

∴ Thus, the perimeter is 76 cm.

Verification:

Here,

⇒ 76 cm = 4 × side

Substitute the values,

⇒ 76 cm = 4 × 19 cm

Multiply the values in RHS,

⇒ 76 cm = 76 cm

∴ LHS = RHS. Hence, proved.
