Kim buys a carpet for a room. The carpet measures 6 metres by 6 metres. Kim pays £390 for the carpet. The room measures 5 metres by 5 metres. Work out the cost of the carpet she does not use.

Area = Length x width

Area of carpet = 6 x 6 = 36 square meters

Cost of carpet per square meter = total cost / area

Cost per square meter: 390 / 36 = £10.83

Area of room = 5 x 5 = 25 square meters.

Area of rug not used = area of room subtracted from area of carpet:

36 - 25 = 11 square meters

Cost of the carpet not used = area of carpet not used x cost per square meter

11 x 10.83 = 119.13

ANSWER: £119.13

Area = Length x width

Area of carpet = 6 x 6 = 36 square meters

Cost of carpet per square meter = total cost / area

Cost per square meter: 390 / 36 = £10.83

Area of room = 5 x 5 = 25 square meters.

Area of rug not used = area of room subtracted from area of carpet:

36 - 25 = 11 square meters

Cost of the carpet not used = area of carpet not used x cost per square meter

11 x 10.83 = 119.13

ANSWER: £119.13

what do you need me to answer?

step-by-step explanation:

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
