Question

the length of a reactangul file is 45m and breadth is 22m this field is to be fenced with barbed wire on it's all side state how much long wire is needed​

Answer 1

Answer:

134 meter

Step-by-step explanation:

perimeter of rectangle :-

$2(l+b)\\=2(45+22) \\=2(67)\\=134$

Thus, the wire should be of 134m

Plz mark me brainliest

Answer 2

Correct Question -

the length of a reactangul field is 45m and breadth is 22m this field is to be fenced with barbed wire on it's all side state how much long wire is nneeded.

Given -

• Length of field = 45m

• Breadth of field = 22m

To find -

• How much long wire is required.

Formula used -

• Perimeter of rectangle = 2(l + b)

Solution -

In the question the length and breadth of the field is given, and has asked, that, how much long wire is required to be fenced. So we will find the perimeter of the field, using the formula of perimeter of rectangle.

So -

Perimeter of field = 2(l + b)

where -

l = Length

B = Breadth

On substituting the values -

Perimeter = 2(l + b)

$\longmapsto$ Perimeter = 2(45m + 22m)

$\longmapsto$ Perimeter = 2(67m)

$\longmapsto$ Perimeter = 134m

$\therefore$ 134m long wire is required ti get fenced.
