31 <h3>Problem 1</h3>

32 <p>Find the length of the square, where the area of the square is 16900 cm².</p>

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

34 <p>The area of a square = a² So, the area of a square = 16900 cm² So, the length = √16900 = 130. The length of each side = 130 cm</p>

35 <h3>Explanation</h3>

36 <p>The length of a square is 130 cm.</p>

37 <p>Because the area is 16900 cm² the length is √16900 = 130.</p>

38 <p>Well explained 👍</p>

39 <h3>Problem 2</h3>

40 <p>Tom is planning to tile his square floor of length 130 feet. The cost to tile a foot is 5 dollars. Then how much will it cost to tile the full floor?</p>

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

42 <p>The length of the floor = 130 feet The cost to tile 1 square foot of floor = 5 dollars. To find the total cost to tile, we find the area of the floor, Area of the floor = area of the square = a² Here a = 130 Therefore, the area of the floor = 130² = 130 × 130 = 16900. The cost to tile the floor = 16900 × 5 = 84500. The total cost = 84500 dollars</p>

43 <h3>Explanation</h3>

44 <p>To find the cost to tile the floor, we multiply the area of the floor by the cost to tile per foot.</p>

45 <p>So, the total cost is 84500 dollars.</p>

46 <p>Well explained 👍</p>

47 <h3>Problem 3</h3>

48 <p>Find the area of a circle whose radius is 130 meters.</p>

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

50 <p>The area of the circle = 53066.8 m²</p>

51 <h3>Explanation</h3>

52 <p>The area of a circle = πr²</p>

53 <p>Here, r = 130</p>

54 <p>Therefore, the area of the circle = π × 130²</p>

55 <p>= 3.14 × 130 × 130</p>

56 <p>= 53066.8 m².</p>

57 <p>Well explained 👍</p>

58 <h3>Problem 4</h3>

59 <p>The area of the square is 16900 cm². Find the perimeter of the square.</p>

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

61 <p>The perimeter of the square is 520 cm</p>

62 <h3>Explanation</h3>

63 <p>The area of the square = a²</p>

64 <p>Here, the area is 16900 cm²</p>

65 <p>The length of the side is √16900 = 130</p>

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

67 <p>Here, a = 130</p>

68 <p>Therefore, the perimeter = 4 × 130 = 520.</p>
