Question

How much fencing would you need to fence in a rectangular storage that measures 40 feet x 20 feet?​

Answer 1

`\Huge \boxed{\mathrm{120 \ feet}}`

Explanation:

The length of the rectangular storage is 40 feet.

The width of the rectangular storage is 20 feet.

The length of fencing is needed to fence the entire rectangular storage.

The perimeter of the rectangle is required.

`P=2l+2w \\ \\ \sf P=perimeter \\ l=length \\ w=width`

`P=2(40)+2(20) \\ \\ P=80+40 \\ \\ P=120`

120 feet of fencing is needed to fence the rectangular storage.

Answer 2

Ammount of fencing required = perimeter of the rectangular storage.

Perimeter of a rectangle = 2(l+b), where l = length, b = breadth.

so perimeter = 2(40+20) = 2(60) = 120 feet

so fencing required = 120 feet
