Question

the length and the breadth of the rectangular plot are 140 m and 60 m. find it's perimeter and the cost of fencing it at the rate of $60​

Answer 1

Answer:

Perimeter= 2(l+b)

= 2(140+60)

=2×200

=400m

Step-by-step explanation:

cost= 400×$60= $24000

Answer 2

Given:-

• Length of a rectangular plot = 135 m
• Breadth of a rectangular plot = 65 m

To Find:-

• It's perimeter and the cost of fencing it at the rate of ₹ 60

Solution:-

$\star\underline{ \frak{ \purple{We \: know \: that}}}$

$\boxed{ \sf{Perimeter_{ (rectangular \: plot) }= 2 (length + breadth)}}$

Putting the values:-

=> 2 (135 + 65)

=> 2 (200)

=> 400 m

Here the cost of fencing = ₹ 60 per m

So the cost of fencing 400 m = 60 × 400
