A rectangular park 200 m long and 120 m wide has two concrete crossroads running in the middle of the park. The rest of the park has been used as a lawn. The width of the crossroads is 20 m. The crossroad has to be covered with bricks such that 300 sq m of bricks can be covered in 1 day. How many days will be taken to cover the crossroad? Correct Answer 20

Given:

The length of the rectangular park is 200 m

The width of the rectangular park is 120 m

Concept:

The area of rectangular park = Length of the park × Width of the park

Calculation:

⇒ The total area of rectangular park = 200 × 120 = 24000 m2

⇒ The area of the cross road = (20 × 200) + (20 × 120) - (20 × 20)

⇒ The area of cross road = 4000 + 2400 - 400 = 6000

⇒ Total taken to cover 300 m2 bricks = 1 day

⇒ Time taken to cover the total cross road = 6000/300 = 20 days

∴ The required result will be 20 days.
