3 <p>The product of multiplying an integer by itself is the square of a number. Squares are used in programming, calculating areas, and so on. In this topic, we will discuss the square of 2.</p>

4 <h2>What is the Square of 2</h2>

5 <p>The<a>square</a><a>of</a>a<a>number</a>is the<a>product</a>of the number with itself. The square of 2 is 2 × 2. The square of a number always ends in 0, 1, 4, 5, 6, or 9. We write it in<a>math</a>as 2², where 2 is the<a>base</a>and 2 is the<a>exponent</a>. The square of a positive and a negative number is always positive. For example, 5² = 25; -5² = 25.</p>

6 <p><strong>The square of 2</strong>is 2 × 2 = 4.</p>

7 <p><strong>Square of 2 in exponential form:</strong>2²</p>

8 <p><strong>Square of 2 in arithmetic form:</strong>2 × 2</p>

39 <h3>Problem 1</h3>

40 <p>Find the side length of a square, where the area of the square is 4 cm².</p>

41 <p>Okay, lets begin</p>

42 <p>The area of a square = a²</p>

43 <p>So, the area of a square = 4 cm²</p>

44 <p>So, the length = √4 = 2.</p>

45 <p>The length of each side = 2 cm</p>

46 <h3>Explanation</h3>

47 <p>The length of a square is 2 cm.</p>

48 <p>Because the area is 4 cm², the length is √4 = 2.</p>

49 <p>Well explained 👍</p>

50 <h3>Problem 2</h3>

51 <p>Lisa is planning to cover her square table of length 2 feet with fabric. The cost to cover a foot of fabric is 3 dollars. How much will it cost to cover the full table?</p>

52 <p>Okay, lets begin</p>

53 <p>The length of the table = 2 feet</p>

54 <p>The cost to cover 1 square foot of table = 3 dollars.</p>

55 <p>To find the total cost to cover, we find the area of the table,</p>

56 <p>Area of the table = area of the square = a²</p>

57 <p>Here a = 2 Therefore, the area of the table = 2² = 2 × 2 = 4.</p>

58 <p>The cost to cover the table = 4 × 3 = 12.</p>

59 <p>The total cost = 12 dollars</p>

60 <h3>Explanation</h3>

61 <p>To find the cost to cover the table, we multiply the area of the table by the cost to cover per foot. So, the total cost is 12 dollars.</p>

62 <p>Well explained 👍</p>

63 <h3>Problem 3</h3>

64 <p>Find the area of a circle whose radius is 2 meters.</p>

65 <p>Okay, lets begin</p>

66 <p>The area of the circle = 12.56 m²</p>

67 <h3>Explanation</h3>

68 <p>The area of a circle = πr²</p>

69 <p>Here, r = 2</p>

70 <p>Therefore, the area of the circle = π × 2² = 3.14 × 2 × 2 = 12.56 m².</p>

71 <p>Well explained 👍</p>

72 <h3>Problem 4</h3>

73 <p>The area of a square is 4 cm². Find the perimeter of the square.</p>

74 <p>Okay, lets begin</p>

75 <p>The perimeter of the square is 8 cm.</p>

76 <h3>Explanation</h3>

77 <p>The area of the square = a²</p>

78 <p>Here, the area is 4 cm² The length of the side is √4 = 2</p>

79 <p>Perimeter of the square = 4a</p>

80 <p>Here, a = 2</p>

81 <p>Therefore, the perimeter = 4 × 2 = 8.</p>

82 <p>Well explained 👍</p>

83 <h3>Problem 5</h3>

84 <p>Find the square of 3.</p>

85 <p>Okay, lets begin</p>

86 <p>The square of 3 is 9.</p>

87 <h3>Explanation</h3>

88 <p>The square of 3 is multiplying 3 by 3. So, the square = 3 × 3 = 9.</p>

89 <p>Well explained 👍</p>
