Question

The length and breadth of a rectangular plot is 50m and 40m respectively. Find the cost of fencing the rectangular plot at rate rs.200 per meter​

Answer 1

Answer:

₹36000

Step-by-step explanation:

Perimeter of the rectangle is

= 2(l + b)

= 2(50 + 40)

= 2 x 90

= 180m

Cost of fencing is 200rs per meter

Cost of fencing for 180m is

= 200 x 180

= 36000 rs

Answer 2

To find : cost of fencing rectangular plot at rate of of Rs $200$ per meter​  .

Given : length = $50 \ m$  and breadth = $40\ m$

Solution :

• According to question we are given that length and breadth  rectangular plot  is $50\ m$ and $40\ m$ respectively. We have to find cost of fencing rectangular plot  

• We find perimeter rectangular plot using  following formula -

• Perimeter of plot $= 2 (l + b )$

• Substituting the values we get,

• Perimeter of plot = $2 ( 50 + 40 )$

                                     $= 2 \times 90$

                                      $= 180\ m$

• To find cost of fencing rectangular plot at rate of of Rs $200$ per meter​ we multiply perimeter by rate of fencing .
• Cost of fencing  = $(180 \times 200)\ Rs$

                                   $= 36000\ Rs$

Hence, cost of fencing rectangular plot is $36000\ Rs$ .
