6). A rectangular piece of land measures 0.5 km by 0.25 km. Each side is to be fenced with 4 rows
of wire. What is the length of the wire needed (in metres).
Answers
Answer:
The length of the wire needed = 6000 meter
Step-by-step explanation:
Given measurements of land which is in rectangular shape
length = 0.5 km = 500 meters [ 1 km = 1000 m ⇒ 0.5 km = 500 m]
breadth = 0.25 km = 250 meters
perimeter of the land = 2 ( length + breadth )
= 2 ( 750 )
= 1500 meters
for 1 row the required wire = 1500 meters
for 4 rows the required wire = 4 × 1500 = 6000 meters
the length of the required wire = 6000 meters
Answer:
6000m of length of fence is needed.
Step-by-step explanation:
- In context to the given question we have to find the length of the wire used to fence the rectangular plot 4 times.
Given,
dimension of the rectangular plot ;
Length = 0.5 km = 500 m
Breadth = 0.25 km = 250 m
( Conversion in m is done because the answer is asked in m )
Perimeter of rectangular plot = Fencing used in one round
Fencing used in one round = 2 ( l + b )
by putting the value of l and b ; we get:
Fencing used in one round = 2 ( 500 + 250)
Fencing used in one round = 2 (750)
Fencing used in one round = 1500 m
therefore,
Fencing with 4 rows = 4 x Fencing used in one round \
Fencing with 4 rows = 4 x 1500
Fencing with 4 rows = 6000m
6000m of length of fence is needed.
