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
