length of wire = circumference of circle
given area of circle enclosed
= 154 cm^2
πr^2 = 154 => r^2 = 154 × 7/22
r^2 = 49 =>r = 7 cm
circumference of circle
= 2πr = 2×(22/7)×7 = 44cm
circumference of circle will be
= perimeter of square
44 = 4×side =>side = 11 cm
side of square = 11cm
area of square enclosed by the wire
= side × side = 11 × 11 = 121cm
Answer: area enclosed by Sqr.= 121cm
