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
