Arectangular room is 1.9 times as long as it is wide, and its perimeter is 33 meters. find the dimension of the room.
length meters
width:
round answers to decimal places.

Length = 10.81 m

Width = 5.69 m

Step-by-step explanation:

Let the width of the room be .

As per question, length is 1.9 times its width.

Therefore, length is,

Perimeter is 33 meters.

Perimeter is given as,

Therefore, width of the room is 5.69 m.

Length of the room is,

Therefore, the length of the room is 10.81 m.

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
