<span>The answer is 6 m.
To arrive at this answer you solve the following equation: {let x = the original length of the garden)
(x+7)^2 = 169
x+7 = 13
x = 13-7
x = 6m</span>

Answer:
Option C is correct.
System of equation which will produce infinitely many solutions:
3x - y = 14        
-9x +3y = -42  
Step-by-step explanation:
From the options 
Only equation which is infinitely many solutions is
3x - y = 14                ......[1]
-9x +3y = -42           ......[2]
For infinitely many solutions, we are looking for linearly dependent equations, which means one equation is an exact multiple or sub-multiple of the other.
Multiply [1] by -3 we get

or
-9x + 3y = -42 which is same equation as [2]
therefore. by definition of infinitely many solution,
equation 2 is -3 times(or multiple) of equation 1
