Answer:
HEY BUDDY HOPE IT HELPS YOU
Step-by-step explanation:
Given :
Length of rectangle ,
l = ( 2x + 3 ) m
Breadth of rectangle ,
b = ( x + 2 ) m
We know ,
Perimeter of rectangle , P = 2 ( l + b )
Now , putting values of l and breadth ,
P = 2 ( 2x + 3 + x + 2 )
= 2 ( 3x + 5 )
= 6x + 10 m
To find : The cost of fencing .
The cost of fencing = Rs 12 per m
= 12 * ( 2x + 10 )
= 24x + 120 Rs
So , the total cost of fencing is Rs. 24x + 120 .
If Rohan whats to fence his garden he will have to pay Rs. 24x + 120 .
