3 <p>The product of multiplying an integer by itself is the square of a number. Square is used in programming, calculating areas, and so on. In this topic, we will discuss the square of 7.</p>

4 <h2>What is the Square of 7</h2>

5 <p>The<a>square</a><a>of</a>a<a>number</a>is the<a>product</a>of the number itself. The square of 7 is 7 × 7. The square of a number always ends in 0, 1, 4, 5, 6, or 9. We write it in<a>math</a>as 7², where 7 is the<a>base</a>and 2 is the<a>exponent</a>. The square of a positive and a negative number is always positive.</p>

6 <p>For example, 5² = 25; -5² = 25.</p>

7 <p>The square of 7 is 7 × 7 = 49.</p>

8 <p>Square of 7 in exponential form: 7²</p>

9 <p>Square of 7 in arithmetic form: 7 × 7</p>

42 <h3>Problem 1</h3>

43 <p>Find the length of the square, where the area of the square is 49 cm².</p>

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

45 <p>The area of a square = a²</p>

46 <p>So, the area of a square = 49 cm²</p>

47 <p>So, the length = √49 = 7.</p>

48 <p>The length of each side = 7 cm</p>

49 <h3>Explanation</h3>

50 <p>The length of a square is 7 cm.</p>

51 <p>Because the area is 49 cm², the length is √49 = 7.</p>

52 <p>Well explained 👍</p>

53 <h3>Problem 2</h3>

54 <p>Sara is planning to tile her square kitchen floor of length 7 feet. The cost to tile a foot is 10 dollars. Then how much will it cost to tile the full floor?</p>

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

56 <p>The length of the floor = 7 feet</p>

57 <p>The cost to tile 1 square foot of floor = 10 dollars.</p>

58 <p>To find the total cost to tile, we find the area of the floor,</p>

59 <p>Area of the floor = area of the square = a²</p>

60 <p>Here a = 7</p>

61 <p>Therefore, the area of the floor = 7² = 7 × 7 = 49.</p>

62 <p>The cost to tile the floor = 49 × 10 = 490.</p>

63 <p>The total cost = 490 dollars</p>

64 <h3>Explanation</h3>

65 <p>To find the cost to tile the floor, we multiply the area of the floor by the cost to tile per foot. So, the total cost is 490 dollars.</p>

67 <h3>Problem 3</h3>

68 <p>Find the area of a circle whose radius is 7 meters.</p>

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

70 <p>The area of the circle = 153.94 m²</p>

71 <h3>Explanation</h3>

72 <p>The area of a circle = πr²</p>

73 <p>Here, r = 7</p>

74 <p>Therefore, the area of the circle = π × 7²</p>

75 <p>= 3.14 × 7 × 7</p>

76 <p>= 153.94 m².</p>

77 <p>Well explained 👍</p>

78 <h3>Problem 4</h3>

79 <p>The area of the square is 64 cm². Find the perimeter of the square.</p>

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

81 <p>The perimeter of the square is</p>

82 <h3>Explanation</h3>

83 <p>The area of the square = a²</p>

84 <p>Here, the area is 64 cm²</p>

85 <p>The length of the side is √64 = 8</p>

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

87 <p>Here, a = 8</p>

88 <p>Therefore, the perimeter = 4 × 8 = 32.</p>

89 <p>Well explained 👍</p>

90 <h3>Problem 5</h3>

91 <p>Find the square of 8.</p>

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

93 <p>The square of 8 is 64</p>

94 <h3>Explanation</h3>

95 <p>The square of 8 is multiplying 8 by 8.</p>

96 <p>So, the square = 8 × 8 = 64</p>

97 <p>Well explained 👍</p>
