Question

please give me the answer fast it's so important​

Answer 1

Solution!!

Width of crossroads = 2.5 m

Length of garden = 35 m

Breadth of garden = 20 m

It is given that the roads are parallel to the length and the breadth of the garden. So,

Length of the first road = 35 m

So, area = Length × Breadth

Area = 35 m × 2.5 m

Area = 87.5 m²

Length of the second road = 20 m

So, area = Length × Breadth

Area = 20 m × 2.5 m

Area = 50 m²

Area of the common path = (Side)²

Area = (2.5 m)²

Area = 6.25 m²

Area of the roads = (87.5 m² + 50 m²) - 6.25 m²

Area of the roads = 137.5 m² - 6.25 m²

Area of the roads = 131.25 m²

Now that we know the area of the roads, we can find out the cost of constructing those roads.

Cost of constructing 1 m² = Rs 100

Cost of constructing 131.25 m² = Rs 100 × 131.25

Cost of constructing the roads = Rs 13,125
