Question

a rectangular plot is 90 cm long and 60 cm wide. two roads. of 1 m each are running parallel to width of the plot and one road of 1 m is running parallel to the length of the plot. find the area covered by road

solve it with solutions

Answer 1

Answer:

149

Step-by-step explanation:

Length of the plot = 90 metres

Width of the plot = 60 metres

Area = length×width

= 90×60

= 5400 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 = 60 m

Area of the road = length×width

= 60×1

= 60 metres

The roads intersect in the middle

Area of the common part of the roads = 1×1 = 1 metre

Area of the roads = 90 + 60 - 1 metre

= 150 - 1 metre

= 149 metres

∴ Area of the roads= 149 metres
