The length and the breadth of a rectangular plot are 135 m and 65 m. Find, its perimeter and the cost of fencing it at the rate of ₹60 per m.
Given :Length (l) = 135 mBreadth (b) = 65 m
Perimeter = 2 (l + b)= 2(135 + 65)= 2(200) = 400 m∴Perimeter of rectangular plot is = 400 mCost of fencing per m = ₹60∴Cost of fencing 400 m = ₹60 x 400 m = ₹24000
