How many paying stones, each measuring 2 1/2 m * 2 m are required to pave a rectangular court yard 30 m long and 16 1/2 m board?

Correct answer: A. 99

  • A. 99
  • B. 90
  • C. 95
  • D. 100Fun & Trivia

Explanation

Each paving stone covers 2.5 m x 2 m = 5 m², while the courtyard covers 30 m x 16.5 m = 495 m². Therefore, 495 m² ÷ 5 m² = 99 stones. A common mistake is option b, 90, usually caused by using an incorrect courtyard breadth or dividing inaccurately.

About Area and Volume

Area measures the surface enclosed by two-dimensional figures, while volume measures the space occupied by three-dimensional solids. Problems use formulas for rectangles, triangles, circles, prisms, cylinders, cones, spheres, and composite figures, including unit conversion and the distinction between surface area, lateral area, and volume.
