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 847.</p>

4 <h2>What is the Square of 847</h2>

5 <p>The<a>square</a>of a<a>number</a>is the<a>product</a>of the number itself. The square of 847 is 847 × 847. The square of a number always ends in 0, 1, 4, 5, 6, or 9. We write it in<a>math</a>as (847²), where 847 is the<a>base</a>and 2 is the<a>exponent</a>. The square of a positive and a<a>negative number</a>is always positive. For example, (52 = 25); ((-5)2 = 25)</p>

6 <p><strong>The square of 847</strong>is 847 × 847 = 717,409.</p>

41 <h3>Problem 1</h3>

42 <p>Find the length of the square, where the area of the square is 717,409 cm².</p>

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

44 <p>The area of a square = (a2)</p>

45 <p>So, the area of a square = 717,409 cm²</p>

46 <p>So, the length = ( √717,409= 847).</p>

47 <p>The length of each side = 847 cm</p>

48 <h3>Explanation</h3>

49 <p>The length of a square is 847 cm. Because the area is 717,409 cm², the length is ( √717,409} = 847).</p>

50 <p>Well explained 👍</p>

51 <h3>Problem 2</h3>

52 <p>Lisa is planning to tile her square floor of length 847 feet. The cost to tile a foot is 3 dollars. Then how much will it cost to tile the full floor?</p>

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

54 <p>The length of the floor = 847 feet</p>

55 <p>The cost to tile 1 square foot of floor = 3 dollars.</p>

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

57 <p>Area of the floor = area of the square = (a2)</p>

58 <p>Here a = 847</p>

59 <p>Therefore, the area of the floor = (8472 = 847 × 847 = 717,409\).</p>

60 <p>The cost to tile the floor = 717,409 × 3 = 2,152,227.</p>

61 <p>The total cost = 2,152,227 dollars.</p>

62 <h3>Explanation</h3>

63 <p>To find the cost to tile the floor, we multiply the area of the floor by cost to tile per foot. So, the total cost is 2,152,227 dollars.</p>

65 <h3>Problem 3</h3>

66 <p>Find the area of a circle whose radius is 847 meters.</p>

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

68 <p>The area of the circle = 2,253,070.29 m²</p>

69 <h3>Explanation</h3>

70 <p>The area of a circle = (pi r2)</p>

71 <p>Here, r = 847</p>

72 <p>Therefore, the area of the circle = (pi × 8472) = (3.14 × 847 × 847 = 2,253,070.29) m².</p>

73 <p>Well explained 👍</p>

74 <h3>Problem 4</h3>

75 <p>The area of the square is 71,740,900 cm². Find the perimeter of the square.</p>

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

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

78 <h3>Explanation</h3>

79 <p>The area of the square = (a2)</p>

80 <p>Here, the area is 71,740,900 cm²</p>

81 <p>The length of the side is ( √71,740,900} = 847)</p>

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

83 <p>Here, a = 847</p>

84 <p>Therefore, the perimeter = 4 × 847 = 3,388.</p>

85 <p>Well explained 👍</p>

86 <h3>Problem 5</h3>

87 <p>Find the square of 850.</p>

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

89 <p>The square of 850 is 722,500.</p>

90 <h3>Explanation</h3>

91 <p>The square of 850 is multiplying 850 by 850. So, the square = 850 × 850 = 722,500.</p>
