There is a rectangular floor of size 336 cm × 420 cm. The floor is to be tiled with largest square tiles. How many such tiles will be required?
Show answer & explanation
Correct answer: C
Explanation
Given:
Length of the floor = 420 cm
Width of the floor = 336 cm
According to the formula:
Side of the largest square tile = HCF (420, 336)
Number of tiles = (Length × Width) / (Side)²
HCF (420, 336) = 84
Number of tiles = (420 × 336) / (84 × 84) = 20 tiles
