Question

find the perimeter of the following squares area is 225cmsq

Answer 1

Answer:

Hope this will help you.........

Step-by-step explanation:

The formula for the area of a square is:

A=s2

Where:

A is the area of the square.

s is the length of the side of a square.

Substituting and solving for s gives:

225 cm2=s2

We can take the square root of each side of the equation giving:

√225 cm2=√s2

15 cm=s

s=15 cm

The formula for the perimeter of a square is:

p=4s

Where:

p is the perimeter of the square.

s is the length of the side of a square.

Substituting for s from the solution for the previous formula and calculating p gives:

p=4×15 cm

p=60 cm

Answer 2

We are given the area of a square

Area = 225 cm²

Using the formula of area of the square we will find the side of the square

Area = ( side )²

225 = ( side )²

side = 15

Now, we will use the formula of the perimeter of the square

Perimeter = 4 × side

               = 4 × 15

               = 60

Hence, the perimeter of the square will be 60 cm
