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?

Question

Area of the park = (60 x 40) m2= 2400 m2.Area of the lawn = 2109 m2.Area of the crossroads = (2400 - 2109) m2= 291 m2.Let the width of the road bexmetres. Then,60x+ 40x-x2= 291x2- 100x+ 291 = 0(x- 97)(x- 3) = 0x= 3.Video Explanation:https://youtu.be/R3CtrAKGxkc
