.

The answer is 13164 Rs

.

Step-by-step explanation:

.

==> Length of the cistern (L) = 25 m

.

==> Breadth of the cistern (B)= 17 m

.

==> Height of the cistern (H) = 8 m

.

==>Area of cistern = LB + 2BH + 2HL

.

= 25 × 17+ (2 × 17 × 8) + (2 × 8 × 25)

.

= 425 + 272 + 400

.

==> Area of cistern = 1097 m^2

.

Now

.

Cost of cementing 1 m^2 area = 12 Rs

.

Cost of cementing 1097 m^2 area = 12 × 1097

.

= 13164 Rs
