Find the size of the largest square slabs which can be paved on the floor of a room 5 meters 44 cm long and 3 meters 74 cm broad?

Correct answer: D. 34

  • A. 56
  • B. 42
  • C. 38
  • D. 34

Explanation

The largest square slab side must divide both floor dimensions exactly. In centimetres, gcd(544, 374) = 34, so the largest slab is 34 cm by 34 cm. The likely mistake is option a, 56, which does not divide both 544 cm and 374 cm.

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.
