the length of a square room is 8m . what will be the cost of carpeting the room with carpet of width 128cm at the rate of Rs 120 per meter?

the length of a square room is 8m . what will be the cost of carpeting the room with carpet of width 128cm at the rate of Rs 120 per meter square?

So to find cost we have to find Area

We know

Total Cost :-

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
