Answer:
Step-by-step explanation:
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. Therefore , the length of the wire needed for the fence is 460 m
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. PLS MARK ME AS BRAINLIEST
Answer:
The cost of fencing is 2,760 rupees.
Step-by-step explanation:
The perimeter of triangle= S1+S2+S3
= 120+80+60
= 260m
They left 10m gap on each side. So, three sides is 30m.
= 260-30
= 230m
The perimeter to fence is 230m.
Cost for fencing 1m= 6 rupees
Cost for double fencing 230m= 230×6×2
= 2760 rupees
