What is the area of a circle whose radius is equal to the side of a square whose perimeter is 8 metres?

Square perimeter = 8m, so each side = 8 ÷ 4 = 2m. This is the circle's radius. Area of circle = πr² = π × 2² = 4π. Using π ≈ 22/7: 4 × 22/7 = 88/7 ≈ 12.57 m². But wait, the options are much larger (1156-1486). Let me recalculate: if the area is 1386 m², then r² = 1386/π = 1386/(22/7) = 1386 × 7/22 = 441. So r = √441 = 21m. For a square with side 21m, perimeter = 84m, not 8m. There's a unit error in the question or options. Assuming the question means perimeter = 88m (not 8m), then side = 22m, radius = 22m, area = π × 22² = (22/7) × 484 = 22 × 69.14 ≈ 1521. None of the options match exactly. However, if we consider 1386 m² with π=22/7: r² = 1386 × 7/22 = 441, r = 21m. This would mean square side = 21m, perimeter = 84m. The question likely has a typo (8 instead of 84), but 1386 m² is the intended answer based on standard values.
