Question

8. A rectangular lawn is 80 m by 40 m. It has two roads of 2 m wide running in the middle one parallel to the length and the other parallel to the breadth. Find the area of the roads please I will mark as brainlist please ​

Answer 1

Answer:

Length of rectangular lawn = 80 m

Breadth = 64 m

Width of road = 5 m

Area of horizontal road =5×80=400m2

Area of vertical road =5×64=320m2

Area of common part to both roads =5×5=25m2

Now,

Area of roads to be gravelled = Area of horizontal road + Area of vertical road − Area of common part to

both roads

=400+320−25

=695 m2

Therefore, Area of roads to be gravelled is 695m2

Cost of gravelling =695× 40=Rs27800
