31 <h3>Problem 1</h3>

32 <p>Find the length of the square, where the area of the square is 24025 cm².</p>

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

34 <p>The area of a square = a² So, the area of a square = 24025 cm² So, the length = √24025 = 155. The length of each side = 155 cm</p>

35 <h3>Explanation</h3>

36 <p>The length of a square is 155 cm.</p>

37 <p>Because the area is 24025 cm² the length is √24025 = 155.</p>

38 <p>Well explained 👍</p>

39 <h3>Problem 2</h3>

40 <p>Anna is planning to paint her square wall of length 155 feet. The cost to paint a foot is 2 dollars. Then how much will it cost to paint the full wall?</p>

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

42 <p>The length of the wall = 155 feet The cost to paint 1 square foot of wall = 2 dollars. To find the total cost to paint, we find the area of the wall, Area of the wall = area of the square = a² Here a = 155 Therefore, the area of the wall = 155² = 155 × 155 = 24025. The cost to paint the wall = 24025 × 2 = 48050. The total cost = 48050 dollars</p>

43 <h3>Explanation</h3>

44 <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 48050 dollars.</p>

46 <h3>Problem 3</h3>

47 <p>Find the area of a circle whose radius is 155 meters.</p>

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

49 <p>The area of the circle = 75425.85 m²</p>

50 <h3>Explanation</h3>

51 <p>The area of a circle = πr²</p>

52 <p>Here, r = 155</p>

53 <p>Therefore, the area of the circle = π × 155²</p>

54 <p>= 3.14 × 155 × 155</p>

55 <p>= 75425.85 m².</p>
