Step-by-step explanation:
total length of wire is 80cm
The wire is cut into two parts, and of these two parts square is made.
the side length of first square is x cm
the side length of second square is y cm.
According to the question,
perimeter of first square is 4x cm
perimeter of second square is 4y cm.
total length of wire = perimeter of first square+ second square
80cm = 4x +4y
80-4x= 4 y
therefore, y= 20-2x
