46 <h3>Problem 1</h3>

47 <p>A garden is shaped like a square, and its area is 241081 square meters. Find the length of each side of the garden.</p>

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

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

50 <p>So, the area of a square = 241081 m²</p>

51 <p>So, the length = (sqrt{241081} = 491).</p>

52 <p>The length of each side = 491 m</p>

53 <h3>Explanation</h3>

54 <p>The length of a square garden is 491 meters.</p>

55 <p>Because the area is 241081 m², the length is (sqrt{241081} = 491).</p>

56 <p>Well explained 👍</p>

57 <h3>Problem 2</h3>

58 <p>A mural is being painted on a square wall of length 491 feet. The cost to paint a foot is 5 dollars. How much will it cost to paint the entire mural?</p>

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

60 <p>The length of the wall = 491 feet</p>

61 <p>The cost to paint 1 square foot of the wall = 5 dollars.</p>

62 <p>To find the total cost to paint, we find the area of the wall.</p>

63 <p>Area of the wall = area of the square = (a2)</p>

64 <p>Here (a = 491)</p>

65 <p>Therefore, the area of the wall = (4912 = 491 × 491 = 241081).</p>

66 <p>The cost to paint the wall = 241081 × 5 = 1205405.</p>

67 <p>The total cost = 1205405 dollars</p>

68 <h3>Explanation</h3>

69 <p>To find the cost to paint the wall, we multiply the area of the wall by the cost to paint per foot. So, the total cost is 1205405 dollars.</p>

71 <h3>Problem 3</h3>

72 <p>Find the area of a circle whose radius is 491 meters.</p>

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

74 <p>The area of the circle = 757912.34 m²</p>

75 <h3>Explanation</h3>

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

77 <p>Here, (r = 491)</p>

78 <p>Therefore, the area of the circle = (pi × 4912) = 3.14 × 491 × 491 = 757912.34 m².</p>

79 <p>Well explained 👍</p>

80 <h3>Problem 4</h3>

81 <p>The area of the square is 241081 m². Find the perimeter of the square.</p>

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

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

84 <h3>Explanation</h3>

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

86 <p>Here, the area is 241081 m²</p>

87 <p>The length of the side is (sqrt{241081} = 491).</p>

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

89 <p>Here, (a = 491)</p>

90 <p>Therefore, the perimeter = 4 × 491 = 1964.</p>

91 <p>Well explained 👍</p>

92 <h3>Problem 5</h3>

93 <p>Find the square of 492.</p>

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

95 <p>The square of 492 is 242064</p>

96 <h3>Explanation</h3>

97 <p>The square of 492 is multiplying 492 by 492.</p>

98 <p>So, the square = 492 × 492 = 242064</p>
