Question

Find the perimeter of a polygon whose side lengths are 5.5ft, 4.59ft, 2.21ft, 6ft and 2.9ft

Answer 1

P=21.2 ft

Explanation:

let

`s_(1)`=5.5 ft

`s_(2)`=4.59 ft

`s_(3)`=2.21 ft

`s_(4)`=6 ft

`s_(5)`=2.9 ft

we have to find perimeter by following formula

P=
`s_(1) +s_(2) +s_(3) +s_(4) +s_(5)`

putting the values in formula

P=5.5+4.59+2.21+6+2.9 ft

P=21.2 ft

Answer 2

The perimeter of a polygon is the sum of each side, so we have three sides, namely:


`s_(1) = 5.5ft`

`s_(2) = 4.59ft`

`s_(3) = 2.21ft`

`s_(4) = 6ft`

`s_(5) = 2.9ft`

Then the perimeter is:


`P = s_(1)+ s_(2)+s_(3)+s_(4)+ s_(5)`

∴
`P = 5.5ft+4.59ft+2.21ft+6ft+2.9ft`

∴
`P = 21.2ft`
