Answer:
616 sq cm or cm^2
Step-by-step explanation:
outside wire = perimeter and circumference
perimeter of square = 4 × side
= 4 × 22
= 88 cm
perimeter of square = circumference of circle
circumference of circle = 2 π r
88 = 2 × 22/7 × r
88 × 7 / 2 × 22 = r
14 cm = radius
area of circle = π r^2
= 22/7 × 14 × 14
= 22/7 × 196
= 22 × 28
= 616 sq cm
