Answer:
Step-by-step explanation:
Length of Rehana's rectangular garden = 14m
Width of the garden = 12m
Area of the garden = l*b = 14*12 = 168m^2
Cost for building a road inside it per square meter = Rs 20
Cost of building it of equal width = Rs 1380
Width of road = 1380/20
= 69m
Therefore , we can conclude that width of the road is 69m
