Question

the length and breadth of a rectangular field are in the ratio 3:2.if the cost of fencing it at Rs.60 per metere​

Answer 1

Answer:

Explanation:

Given :

• Length and breadth of a rectangular field are in the ratio 3:2.
• Rate = Rs. 60 per meter

To Find :

• Cost of fencing.

Solution :

Given that, Length and breadth of a rectangular field are in the ratio 3:2.

=> l = 3 m and b = 2 m

We know that,

Perimeter of rectangular field = 2(l + b)

=> Perimeter = 2(3 + 2)

=> Perimeter = 2(5)

=> Perimeter = 10 m

Now,

Cost of fencing = Perimeter × Rate

=> Cost of fencing = 10 × 60

=> Cost of fencing = Rs.600

Hence :

The cost of fencing of rectangular field is Rs. 600.

$\Large \rm{ \underline { \pink{GIVEN : }}}$

$\huge\pink\star$Ratio of length & breadth of a rectangular field = 3:2.

$\huge\pink\star$Rate = Rs. 60 per meter.

$\Large \rm{ \underline { \pink{TO \: FIND : }}}$

$\huge\pink\star$The cost of fencing of a rectangular field.

$\Large \rm{ \underline { \pink{SOLUTION : }}}$

$\huge\pink\star$Length = 3 m

$\huge\pink\star$Breadth = 2 m

Perimeter of rectangular field = 2(Length+ Breadth)

➜ Perimeter of rectangular field = 2(3+2)

➜ Perimeter of rectangular field = 2(5)

➜ Perimeter of rectangular field = 10 m

Cost of fencing = Perimeter × Rate

➜ Cost of fencing = 10 × 60

➜ Cost of fencing = Rs.600

$\boxed{{\sf\pink{Hence, \: the \: cost \: of \: fencing \: of \: a \: rectangular \: field \: is \: Rs.600}}}$
