Question

a classroom has a length of 20 feet and a width of 30 feet. The headmaster decided that tiles will look good in that class. if each tile has a length of 2 ft and a width of 3 ft, how many tiles are needed to fill the classroom

Answer 1

The area of the room must equal the sum of the areas of the tiles...

20*30=n(2*3)

600=6n

n=100

So 100 tiles are needed.

Answer 2

Hello there.

Question: A classroom has a length of 20 feet and a width of 30 feet. The headmaster decided that tiles will look good in that class. if each tile has a length of 2 ft and a width of 3 ft, how many tiles are needed to fill the classroom

Answer: Work out the area of one tile first:
3 x 2 = 6ft².
Work out the area of the classroom:
20 x 30 = 600ft².
Divide the two values:
600/6 = 100.

In short, 100 tiles are needed.

Hope This Helps You!
