My son has a math homework that neither he nor i know the answer can anybody us? : helen's house is located on a rectangular lot that is 1 1/8 miles by 9/10 mile. estimate the distance around the lot.

The distance around lot is 4 miles

Solution:

Given that the rectangular lot is mile by mile

To find: Distance around the lot

Distance around the lot means we have to find the perimeter of rectangular lot

From given question,

The perimeter of rectangle is given as:

perimeter = 2(length + width)

Substituting the length and width, we get

Thus distance around lot is 4 miles

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.
