Question

The measure of one side of a square is (s + 3) inches long.Writes two different equivalent expressions that represent the perimeter of the square. How can I do this it's hard

Answer 1

Answer:

Therefore Perimeter of a Square,

1. $Perimeter =(s+3)+(s+3)+(s+3)+(s+3) =4s+12$

2. $Perimeter=4(s+3)=4s+12$

Step-by-step explanation:

Given:

The measure of one side of a square is (s + 3) inches long,

∴ length of a side of square is  (s+3) inches

Let the Perimeter of a Square be "P"

To Find:

P =?

Solution:

Square:

For a Square all sides are EQUAL.

Perimeter of Square:

Sum of all the sides.

It's Formula is given by,

$Perimeter=4\times (side)$

side = length of a side of square

Substituting the values we get

$Perimeter =4(s+3)$

Applying Distributive Property A(B+C)=AB+AC we get

$Perimeter =4s+4\times 3\\Perimeter=4s+12$

Both the Expression is Equivalent

Also you can get it by adding sides 4 times ,

$Perimeter =(s+3)+(s+3)+(s+3)+(s+3)=4s+12$

Therefore Perimeter of a Square,

1. $Perimeter =(s+3)+(s+3)+(s+3)+(s+3)=4s+12$

2. $Perimeter=4(s+3)=4s+12$
