Question

Help me write an expression to find perimeter.

Answer 1

Perimeter,
`P=(2)/(5)(5x+14)`

Explanation:

We have, a hand woven rectangular rug measures x ft long and
`2(4)/(5)\ ft` wide. For a rectangular shaped object, perimeter is equal to the sum of all sides. If l is length and b is width, then

Perimeter,
`P=2(l+b)`

We have, l = x ft and b =
`2(4)/(5)\ ft=(14)/(5)\ ft`

So,

`P=2(x+(14)/(5))`

or

`P=(2)/(5)(5x+14)`
