Apool measuring 18 meters by 28 meters is surrounded by a path of uniform width. if the area of the pool and the path combine is 936 meters what is the width of the path

  4 meters

Step-by-step explanation:

If the path has width w meters, the overall dimensions of the pool area are ...

  (18+2w) by (28+2w)

so the overall area in square meters is ...

  (18 +2w)(28 +2w) = 936

  4w² + 92w -432 = 0 . . . . . subtract 936 and eliminate parentheses

  w² + 23w -108 = 0 . . . . . . . divide by 4

  (w +27)(w -4) = 0 . . . . . . . . factor

The positive solution to this equation is w = 4.

The width of the path is 4 meters.

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.
