Given that a rectangular yard has dimensions length = 8x-3 and width 2x+6 determine the perimeter of the yard

The perimeter of rectangular yard is 20 x + 8   yard

Step-by-step explanation:

Given as :

The length of the rectangular yard = L = 8 x - 3   yard

The width of the rectangular yard = w = 2 x + 6   yard

Let The perimeter of rectangular yard = p yard

According to question

Now, The perimeter of rectangular yard is given as

Perimeter = 2 × Length + 2 × width

Or, p =  2 × L + 2 × w

Or, p = 2 × (8 x - 3) + 2 × (2 x + 6)

Or, p = 16 x - 6 + 4 x + 12

Or, p = (16 x + 4 x) + (12 - 4)

Or, p = 20 x + 8   yard

So, The perimeter of rectangular yard = p = 20 x + 8   yard

Hence The perimeter of rectangular yard is 20 x + 8   yard    Answer

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.
