A gardener has to put a double fence all around a triangular path with sides 120m, 80m and 60m. In the middle of each side there is a gate of width 10m. Find the length of the wire needed for the fence.
Answers
Answer:
we have to calculate the perimeter of triangular field
sides will be 120-10,80-10,60-10
110,70,50
perimeter=2 (110+70+50)=2×230
460m
Ans=460m wire needed for the fence
The length of the wire needed for the fence is 460 m .
Explanation:
Given : A gardener has to put a double fence all around a triangular path with sides 120m, 80m and 60m.
In the middle of each side there is a gate of width 10m.
The perimeter of triangle = Sum of all sides
= 120+80+60 = 260 m
Now , the length of wire needed for fence = 2 x ( Perimeter of triangle - 3(10))
= 2 x(260-30) = 2 x (230) = 460 m
Therefore , the length of the wire needed for the fence is 460 m .
