Answer:
165sqft
Given:
A rectangular tile is 2 inches by 3 inches
To find:
area
Step-by-step explanation:
Correct option is B)
We first need to calculate HCF of the dimensions of the floor.
8m70cm=870cm and 6m38cm=638cm
Finding HCF of 870;638, we have
Prime Factorisation of 870=2×3×5×29
638=2×11×29
We then choose each common prime number with the least power and multiply them to get the HCF.
=>HCF=2×29=58
So the dimensions of each square till be 58cm
Now, least number of square tiles required =
Area of each tile x Area of the floor
= 58×58
870×638
=165
