Fractions, Decimals and ApproximationA rectangular lawn has an area of 1815 square yards. If its length is 50 metres, find its width in metres, given that 1 metre equals 1.1 yards.
- A.39.93
- B.35.00
- C.33.00
- D.30.00
Show the answer and explanation
Answer: D (30.00)
Explanation
1 m = 1.1 yd, so 1 m² = 1.1 × 1.1 = 1.21 sq yd. The area is 1815 ÷ 1.21 = 1500 m², so the width is 1500 ÷ 50 = 30 m.
