Question

A rectangular park 60 m long and 40 m wide has two concrete crossroads running in the middle of the park and the rest of the park has been used as a lawn. What is the width of the road if the area of the lawn is 2109 m2?

Answer 1

Answer:

length = 6om

breadth=40m

area of the park=6ox 40=2400m2

area of the lawn=2109m2

area of the cross roads=24oo-2109

=291m2

The width of the road be x m

(6o-x) x+(4o-x) x=291

6ox-x2+4ox-x2=29 I
