The answer is 4 feet.

Step-by-step explanation:

A rectangular deck is 12 ft by 14 ft.

When the length and width are increased by the same amount, the area becomes 288 sq. ft.

Area is given as = length x width

Let the dimensions be increased by 'x' units.

So, we can say that

Solving this we get,

Arranging in a proper way we get;

This gives factors: (x+30) and (x-4)

This further gives either x = -30 (neglecting the negative value)

And x = 4

So, the dimensions were increased by 4 feet.

We can check this by finding the area.

Putting x = 4, we get;

feet square

Therefore, the answer is 4 feet.
