A rectangular park 60 m long and 40 m wide has two concrete crossroads running in the middle of the park and rest of the park has been used as a lawn. If the area of the lawn is 2109 sq. m, then what is the width of the road?	Choose the correct choice
A) 1
B) 2
C) 3
D) 4
E) 5
Explanation:   Area of the park = (60 x 40) = 2400m2   Area of the lawn = 2109m2   Area of the crossroads = (2400 - 2109)=

<output>291</output>
291m2   Let the width of the road be x metres. Then,   60x +40x - x2= 291   x2 - 100x + 291 =0   (x - 97)(x - 3) = 0   x = 3. Answer: 3
