Question

find the length of barbed wire to go round three times the boundary of a rectangular field 28m 50cmlong and 22m75cm wide
step by step explanation please ​

Answer 1

length of barbed wire = circumference of rectangle

C = 2 * (l + W)

so , we know that given in question that

Length = 28.5 m , Breadth = 22.75 m

then ,

C = 2*(22.75+28.5) = 2*(51.25) = 102.5 m

• so , Length of Barbed wire = 102.5 m
