Question

A rectangular plot of land is 50 m long. The cost of leveling the plot at the rate

of Rs. 8 per metre square is Rs. 8000. Find:

(i) The breadth of the plot.

(ii) The cost of fencing the plot at the rate of Rs. 30 per metre.​

Answer 1

Answer:

THE BREADTH=20m

COST OF FENCING =30000

AREA OF RECTANGLE = 8000/8=1000

LENGTH =50M

BREADTH=?

THEREFORE,

BREADTH = AREA OF THE REACTANGLE ÷ LENGTH

THEREFORE, BREADTH = 1000÷50=20

NOW THE COST OF FENCING RS.30 PER METRE SQUARE = 30×1000

=₹30000
