Answer:

Length of the monument=80 m,Total cost of fencing=Rs.3000(if we take Rs.15/m and not Rs.15/m2)

Step-by-step explanation:

Given:

one side of square mall=40 m

area of square mall=1600m2

breadth of rectangular monument=20 m

To find:

length of rectangular monument and total cost of fencing around the monument.

(1)Length of rectangular monument

area of square =area of rectangle

1600=(l)(b)

1600=20(l)

l=1600/20

l=80 m

(2)total cost of fencing around the monument

=(15)(perimeter of monument)

=(15)(80+20+80+20)

=(15)(200)

=Rs.3000
