Answer:
204 cm
Step-by-step explanation:
P of square = 4×Side
= 4×7
= 28cm
C of circle = 2πr
But the radius is not given. We know that radius is half of diameter.
So, r = 14/2
= 7
π = 22/7
C of circle = 2× 22/7×7
= 2×22 ( 7 gets cancelled)
= 44cm
Length of wire = P of square + P of circle
= 28cm + 4(44)
= 28+176
Therefore the length of wire = 204cm
