Answer:

The dimensions of rectangular fence are 14 feet and 20 feet.

Step-by-step explanation:

We are given the following in the question:

Length of rectangular fence = 14 feet

Width of fence = (14+x) feet

Area of rectangular field = 280 square feet

Area of rectangular field =

[tex]A= \text{Length}\times \text{Width}[/tex]

Putting the values, we get,

[tex]280 = 14(14+x)\\\\14 + x = \dfrac{280}{14}\\\\14 + x = 20\\x =20-14\\x = 6[/tex]

Thus, the dimensions of rectangular fence are 14 feet and 20 feet.
