Math Problem Statement

The perimeter of a square is 6.4 meters. What is its area

Solution

To find the area of a square, we can first determine the side length from the perimeter and then use that to calculate the area.

  1. Step 1: Use the formula for the perimeter of a square: P=4sP = 4s where PP is the perimeter and ss is the side length of the square.

    Given that P=6.4P = 6.4 meters, we can solve for ss: s=P4=6.44=1.6 meterss = \frac{P}{4} = \frac{6.4}{4} = 1.6 \text{ meters}

  2. Step 2: Now, to find the area AA of the square, use the formula: A=s2A = s^2 Substituting the value of s=1.6s = 1.6 meters: A=(1.6)2=2.56 square metersA = (1.6)^2 = 2.56 \text{ square meters}

Therefore, the area of the square is 2.56 square meters.

Here are 5 related questions to expand your understanding:

  1. How would the area change if the perimeter of the square was doubled?
  2. If the side length of the square is 2 meters, what is its perimeter?
  3. How does the perimeter of a rectangle compare with a square if they both have the same area?
  4. What is the length of the diagonal of this square?
  5. How does the area of a square relate to its side length in general?

Tip: For any square, the side length can be easily found by dividing the perimeter by 4!
