The floor of a room is being covered with tile. an area three fourths
of the length and three fifths
of the width is covered. find the fraction of the floor that has been covered.

 9/20 of the area is covered.

Step-by-step explanation:

1, You have that the area can be calculated with the formula shown below:

2. You know that the 3/4 of the lenght and 3/5 of the width is covered.

3. Then, the area is:

4. Multiply the fractions shown above, then you obtain:

5. Therefore, 9/20 of the area is covered.

9/20 part of the total area of the floor is covered.

Step-by-step explanation:

Let the length of a room is = L and width of that room is = W

Then area A of the room will be = length × width = L×W

Now an area of this room is to be covered by the tiles,of which Length (L') is = and width (W') =

So the area A' covered by the tiles will be =

So 9/20th part of floor has been covered.

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply

            divide both sides by 32
