7cm

Explanation:

Answer 2

The length of the shorter piece of wire is 7cm

Explanation:

Let us assume that wire is cut into two parts of lengths x and y

Here x is the length of shorter piece and y is the length of longer piece .

Also given that y=x+2

x+y=16cm

From above equations we can write

x+x+2= 2x+2= 16

2x= 14

x= 7cm
