Apiece of cloth is folded into a square with a side length measuring x inches. when it is unfolded, it has an area of x2 + 27x + 162 square inches. which could be the dimensions of the rectangular piece of cloth when it is unfolded? remember, the area of a rectangle can be determined using the formula a = lw. a).length = (x + 9) inches and width = (x + 3) inches b).length = (x − 3) inches and width = (x − 9) inches c).length = (x + 18) inches and width = (x + 9) inches d).length = (x − 9) inches and width = (x − 18) inches

answer is : muchas/tipicas

have a nice day!

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.
