Answer:
68.47 m
Step-by-step explanation:
Data provided:
The shape of the yard as rectangular
Length of the gate = 3.13 m
Sides of the yard = 14.2 m
Length of the yard = 21.6 m
Therefore,
The total length of the fence
= Perimeter of the rectangular yard - Length of the gate
or
= 2 ( Side of the yard + Length of the yard ) - Length of the gate
= 2 ( 14.2 + 21.6 ) - 3.13
= 71.6 - 3.13
or
The total length of the fence = 68.47 m
