Question

The perimeter of a square picture frame is 5.4 inches . What is the length of one side? Write and equation and slove.

Answer 1

4x=5.4

1.35 in.

Explanation:

1. Since it's a square, each side is of equal length

2. Since there's four sides of a square you need to divide 5.4 (perimeter) by four to find the length of one side.

3. 4x=5.4

4. Divide each side of the equation by 4 find x (the length of one side)

5. x=1.35 in.

Answer 2

s = 1.35 (See explanation!)

Explanation:

To write an equation, you need to know that all four sides of a square are equal. Since each side is equal, it can be represented by the same variable or value. I'll use s for the variable:

Equation:

4s = 5.4

Note: the 4s is the total perimeter (4 * side)

Now, solve:

4s = 5.4

Divide by four to isolate the s:

4s/4 = 5.4/4

Finally:

s = 1.35
