Alika [10]

Answer:

The Original length of the wire is 61.1 cm.

Step-by-step explanation:

Given:

l-12.5=48.6

Now it has been given that the above equation can be used to find the original length in centimeters of a wire before it was cut.

Also We need to find the original length of the wire.

From above equation we can say that;

l ⇒ Original length of the wire.

On Solving the above equation we get;

l-12.5=48.6

Now we will add both side by 12.5 using addition property of equality.

l-12.5+12.5 =48.6+12.5\\\\l =61.1\ cm

Hence the Original length of the wire is 61.1 cm.
