The Ratio is 9 : 4.
Answer:
149 metres
\mathfrak{Explanation}Explanation
Length of the plot = 90 metres
Width of the plot = 40 metres
Area = length×width
= 90×40
= 3600 metres
Width of the road parallel to the length = 1 metre
Length of the road parallel to length = 90 metres
Area of the road = length×width
= 90×1
= 90 metres
Width of the road parallel to the breadth = 1 metre
Length of the road parallel to the breadth = 40 m
Area of the road = length×width
= 40×1
= 40 metres
The roads intersect in the middle
Area of the common part of the roads = 1×1 = 1 metre
Area of the roads = 90 + 40 - 1 metre
= 130 - 1 metre
= 129 metres
∴ Area of the roads= 129 metres
