Answer:
Step-by-step explanation: length of wire= 88 cm = circumfrence of circle.
hence, 2*π*r=88cm
=2*22/7r=88
=r=88*7/2*22
=r=14 cm
area=π*r*r
= 22/7*14*14
=28*22
=616cm²
length of wire = 88 cm
perimeter of square =88cm
=4side=88
side=88/4
side=22cm
area=side*side
area=22*22
=484cm²
Therefore circle has the larger area.

Step-by-step explanation:
Length of the wire=88 cm
Hence,2×π×r=88
=r=88×7/2×22
=r=14 cm
Area=π×r×r
=22/7×14×14
=28×22
=616cm²
Length of wire =88 cm
Perimeter of the square=88 cm
=4 side=88 cm
side=88/4
side=22 cm
Area=side×side
Area=22×22
=484cm²
Therefore circle has larger area.....
