There is a rectangular floor of size 540 cm × 720 cm. The floor is to tiled with largest square tiles. How many such tiles will be required?
Show answer & explanation
Correct answer: D
Explanation
Given:
Length = 720 cm, Width = 540 cm
According to the formula:
Side of the largest square tile = HCF (Length, Width)
Number of tiles = (Length × Width) / (Side)²
HCF (720, 540) = 180
Number of tiles = (720 × 540) / (180 × 180) = (4 × 3) = 12
