9 cm
Step-by-step explanation:
First, find the length of the wire by finding the perimeter of the rectangle
2(7) + 2(11) = 36 cm
A square has 4 equal sides, therefore:
36/4 = 9 cm is the length of the side
9cm
Step-by-step explanation:
The length of the wire = the perimeter of the rectangle = (7 + 11) x 2 = 36cm
Because A square has 4 equal sides: 36/4 = 9cm = the side of the square
