How many meters of carpet 50cm, wide will be required to cover the floor of a room 30m * 20m?
Correct answer: D. 1200
- A. 1000
- B. 600
- C. 2400
- D. 1200
Explanation
The floor area is 30 m x 20 m = 600 m2. A carpet strip 50 cm wide has width 0.5 m, so its required length is 600 m2 / 0.5 m = 1200 m. The likely alternative is 600 m, option b, which forgets to divide by the carpet width.

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.
