Question

a floor tile measures 60 CM by 15 CM what area of the floor can be covered by 100 of the tiles​

Answer 1

Answer:

Solution:

We will be using the area of rectangle formula to calculate the area o the rectangular region and the tiles.

We know that, the area of a rectangle is given by length × breadth

(a) Area of rectangular region = 100 × 144

= 14400 cm

Also, area of one tile = 5 × 12

= 60 cm2

The number of tiles needed = Area of the rectangular region / Area of one tile

= 14400 / 60

= 240

Hence, 240 tiles are needed in this case.

(b) Now, area of rectangular region = 70 × 36

= 2520 cm2

Also, area of one tile = 5 × 12

= 60 cm2

The number of tiles needed = Area of the rectangular region / Area of one tile

= 2520 / 60

= 42

Hence, 42 tiles are needed in this case.

Therefore, 240 tiles are required in
