Question

a square field is 45m long. how much wire will be required for fencing three times.

Answer 1

Length of wire required for fencing one time
= Perimeter of the field
= 4 x length of side
= 4 x 45m
= 180m

Length of wire required for fencing three times
= 180 x 3
= 540m

Answer 2

perimeter = 4 X 45
180m
then, 3 X 180
540m
