Question

a rectangular field measure 40 meters by 120 meters if the
field is to be fenced with 4 lines of wires, find the length
of wire required​

Answer 1

Answer:

Length = 120 m

Breadth = 40 m

Hence,

Perimeter= 2(l+b)

= 2(120+40)

= 2 × 160

= 320 m

320 × 4 = 1280m

Step-by-step explanation:

Hope this answer will help you.

Answer 2

➤ Given :-

Length of the rectangle :- 120 metres

Breadth of the rectangle :- 40 metres

➤ To Find :-

Length of wire required to fence with 4 lines........

➤ Solution :-

First, we should find the perimetre of the rectangular field by adding length and breadth and multiplying by 2..........

Perimeter of the rectangle :-

${\tt \longrightarrow 2 \: (length + breadth)}$

${\tt \longrightarrow 2 \: (120 + 40)}$

${\tt \longrightarrow 2 \: (160) = \boxed{\tt 2 \times 160}}$

${\tt \longrightarrow 320 \sf \: \: metres}$

Now,

Length of wire required to fence :-

${\tt \longrightarrow 320 \times 4}$

${\tt \longrightarrow 1280 \sf \: \: metres}$

$\Huge\therefore$ The length of wire required to fence the park with four lines is 1280 metres.

$\dashrightarrow$ Some related formulas :-

Area (rectangle) :- ${\boxed{\tt Length \times Breadth}}$

Length (rectangle) :- ${\boxed{\tt\dfrac{Area} {Breadth}}}$

Breadth (rectangle) :- ${\boxed{\tt\dfrac{Area} {Length}}}$
