Answer 1

answer

Answer

Here the area and the width of the rectangular fence are given. We have to find length of the fence.

( diagram )

The area A of a rectangle is given by the formula A=lw where l is the length and w is the width.

Given that area is 500 square feet and width is 20 feet.

Substituting values in formula,

⇒500=l×20

⇒

20

500

=

20

1×20

[ Dividing both sides by 20 ]

⇒l=25 feet

∴ length of rectangular fence is 25 feet.

Hence, the answer is 20.
