Q. Ben likes to go in the covered dome when he feels overexcited. The dome covers an area of 123 1 \frac{2}{3} square meters, which is 5840 \frac{5}{840} of the total area of the playground.\newlineWhat is the total area of the playground?\newlinesquare meters
  1. Understanding the Relationship: Understand the relationship between the area of the dome and the total area of the playground.\newlineThe problem states that the area of the dome is 1(23)1\left(\frac{2}{3}\right) square meters, which is also given as (5840)\left(\frac{5}{840}\right) of the total area of the playground. This means that if we let AA represent the total area of the playground, then the area of the dome is a fraction of the total area.
  2. Converting to Improper Fraction: Convert the mixed number to an improper fraction to represent the area of the dome.\newline1231\frac{2}{3} can be converted to an improper fraction by multiplying the whole number by the denominator of the fraction and adding the numerator, then placing that result over the original denominator.\newline123=(1×3+2)/3=(3+2)/3=531\frac{2}{3} = (1 \times 3 + 2)/3 = (3 + 2)/3 = \frac{5}{3} square meters
  3. Setting up the Equation: Set up the equation to find the total area of the playground. Since the area of the dome is (5840)(\frac{5}{840}) of the total area of the playground, we can write the equation: (5840)×A=53(\frac{5}{840}) \times A = \frac{5}{3}
  4. Solving for Total Area: Solve for AA, the total area of the playground.\newlineTo find AA, we need to divide both sides of the equation by (5/840)(5/840):\newlineA=5/35/840A = \frac{5/3}{5/840}
  5. Simplifying the Equation: Simplify the equation by multiplying by the reciprocal of (5840)(\frac{5}{840}).A=(53)×(8405)A = (\frac{5}{3}) \times (\frac{840}{5})
  6. Canceling Common Factors: Cancel out the common factors of 55 in the numerator and denominator.\newlineA=(13)×(8401)A = \left(\frac{1}{3}\right) \times \left(\frac{840}{1}\right)
  7. Finding the Total Area: Multiply the remaining fractions to find the total area.\newlineA=8403A = \frac{840}{3}\newlineA=280A = 280 square meters
