By pythagoreans' theorem, Longer edge = √(2² + 6²) = √40 ∴ The length of the longer edge is the square root of 40 feet. Shorter edge = √(1² + 3²) = √10 Area = L × B = √40 × √10 = 20 feet²

Minimum = 5 maximum = 50 Q1 = (15 + 20)/2 = 17.5 Q2 (median) is 25 Q3 = (35 + 40)/2 = 37.5
20% of $50 = $10
30% of $50 = $15
40% of $50 = $20
Multiply 20% by $50
30% by $50
40% by %50
