The breadth of a rectangular park is of 480m. If 3km.72m long wire is required for fencing it find the length of the park
Answers
Answer:
1 km 56 m
Step-by-step explanation:
Fencing is done by knowing the perimeter of the given shape of plot.
Hence to find length of the rectangular park we have to use the concept of perimeter for a rectangle
Given, breadth of the park = 480 m
Given, perimeter of the park = 3 km 72 m
= 3072 m
Length of the park = let it be l m
Now, formula for perimeter of rectangle is
= 2(l + b)
So, 3072 = 2(l + 480)
(l + 480) = 3072/2
l + 480 = 1536
l = 1536 - 480
l = 1056 m
The length of the park is 1056 m or 1 km 56 m.

ANSWER
1km and 56 m
Step-by-step explanation:
=》breath of park = 480m
=》let length of park = l
since, length of wire will cover the boundry .
so, length of wire = perimeter
=》 perimtre = 3km 72m
since, 1km = 1000m
therefore 3km = 3× 1000 m
= 3000m
so, total perimeter = (3000+ 72) m
= 3072 m
=》 perimeter of rectangle= 2(l+b)
=》 3072 = 2(l + 480)
=》 3072/2 = l+ 480
=》 1536 = l+ 480
=》 1536 - 480 = l
=》 1056 = l
therefore, length of the park = 1056 m or 1km 56m.
