Answer:
Length = 32 metres
Explanation:
Cost of constructing a boundary wall around a rectangular plot = Rs.20,480
Cost per meter-Rs.40
Thus, The total area= 20,480/40 = 512 meters squared
Area of a rectangle =length x breadth
Length of a rectangle= area/breadth
(Breadth = 16 meters)
Thus, 512/16=32
Thus, the length of the rectangular plot is 32 meters
