rectangular tiles each of side 70 cm by 30 cm must be laid horizontally on a rectangular of size 110 CM by 130 cm such that the tires do not overlap I tell can be replaced in any orientation so long as it adjust are parallel to the ages of the floor not I will should overshoot any age of the floor what is your maximum number of times that can be operated on the floor

Answer 1

The answer is given below :

The area of the rectangular floor

= 110 × 130 cm²

= 14300 cm²

and

the area of each rectangular tile

= 70 × 30 cm²

= 2100 cm²

Thus number of tiles needed

= area of the floor ÷ area of each tile

= 14300 ÷ 2100

= 6.8

So, maximum number of tiles needed = 7

Thank you for your question.
