Answer 1

Answer:

Hellow................................

Answer 2

Step-by-step explanation:

We know that for the road ABCD

It is given that length = 75m and breadth = 4m

We know that

Area of road ABCD =l×b

By substituting the values

Area of road ABCD = 75×4

So we get

Area of road ABCD = 300m

2

We know that for the road PQRS

It is given that length = 60m and breadth = 4m

We know that

Area of road PQRS =l×b

By substituting the values

Area of road PQRS = 60×4

So we get

Area of road PQRS = 240m

2

We know that for road EFGH

It is given that side = 4m

Area of road EFGH = side

2

By substituting the value

Area of road EFGH =4

2

=16m

2

The total area of the road for gravelling = Area of road ABCD + Area of road PQRS - Area of road EFGH

By substituting the values

Total area of the road for gravelling = 300 + 340 – 16

So we get

Total area of the road for gravelling = 524m

2

It is given that the cost of gravelling the road = ₹50perm

2

So the cost of gravelling 524m

2

road = ₹(50×524) = ₹26200

Therefore, the cost of gravelling the road is ₹26200.
