Answer 1

Answer:

9ft

Step-by-step explanation:

14 ft (top) - 5ft (bottom) = missing side (which is 9ft)

Answer 2

Answer:

9ft

Step-by-step explanation:

suppose that the side of 7ft was dragged to the right till it meets the side of 4ft

and the unknown side was dragged downwards till it meets the side of 5ft

Then, also considering that all angles are right angles, this structure becomes a square.

So the answer is 14ft - 5ft = 9ft
