A square is dilated by a scale factor of 4/5 to create a new square. What is the relationship between the new area and the original area? A. The area of the new rectangle is 16/5 the original area.
B. The area of the new rectangle is 64/125 the original area.
C. The area of the new rectangle is 4/5 the original area.
D. The area of the new rectangle is 16/25 the original area.

C. The area of the new rectangle is 4/5 the original area.

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.
