A rectangular park is 45 m long and 30 m wide. A 2.5 m wide path is constructed all along outside the park. The area of the path is :
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 400 m2
A path all along the outside adds its width on both sides of each length, so the outer rectangle is \(2\times2.5=5\) m longer and 5 m wider than the park. The path is the outer rectangle minus the park.
Outer rectangle: \(50\times35=1750\) m2
Park: \(45\times30=1350\) m2
Path: \(1750-1350=400\) m2
