Answer 1

$\huge\underline\red{\sf CorrectQuestion :-}$

★ A rectangular plot of land is 40m long by 200m wide.The cost of fencing per meter is Rs 30. What is the cost of fencing the entire field? ★

Given:

• Length and Breadth of rectangle is 40 m and 200 m respectively
• Cost of fencing is Rs 30 per m

To Find:

• Cost of fencing the field i.e Perimeter

Solution: Perimeter of Rectangle= 2(l+b)

$\small\implies{\sf }$ 2 ( 40 + 200 )

$\small\implies{\sf }$ 2 ( 240) = 480 m

☆Cost of Fencing per meter = Rs 30 ☆

$\small\implies{\sf }$ Total Cost = Perimeter x Cost per meter

$\small\implies{\sf }$ 480 x 30

$\small\implies{\sf }$ Rs 1440

Hence Cost of fencing the entire field will be Rs 1440

Answer 2

$\large \bigstar\boxed{\bf \red{ GIVEN}} \bigstar$

• Length of plot = 40 m
• Breadth of plot = 200 m
• cost of fencing /m² = Rs 30

$\large \bigstar\boxed{\bf \red{TO\: FIND}} \bigstar$

• Cost of fencing the entire field

__________________________

$\large \bigstar\boxed{\bf \red{SOLUTION}} \bigstar$

$\\ \boxed{ \bf \blue {Perimeter \: of \: rectangle = 2(l + b}} \\ \\ \Rightarrow \bf 2(40 + 200) \\ \\ \Rightarrow \bf2 \times 240 \\ \\ \Rightarrow \bf 480 \:{m}^{2}$

• Cost of fencing for 1 m² = 30 rs

• Cost of fencing for 480 m²

• 480 x 30 = 14400 rs

$\boxed{ \bf \orange {Cost \: of \: fencing = 14400 \: rs}}$
