Answer:

Step-by-step explanation:

first you would need to find the perimeter in order to find the cost of fencing.

x(7x)=1792

7x^2=1792

x^2=256

x=16

so you have x which is the width. now time to find the length

16 times 7 is 112

112 is your width

112+112+16+16 is 256, which is your perimeter.

256 times 1.5 is your cost, or 384 rupees
