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. The area of the lawn is 2109 sq. m. what is the width of the road?
Select the correct option.
A) 5 M B) 4 M C) 2 M D) 3 M E) 6 M
AREA OF THE PARK = 60 * 40=

<output>2_400</output>
2400 M^2   GIVEN AREA OF THE LAWN= 2109 M^2   TOTAL AREA OF THE CROSS ROA3 MS = 2400 - 2109= 
<gadget id="calculator">2400 - 2109</gadget>
<output>291</output>
291 M^2   ASSUME THAT THE WI3 MTH OF THE CROSS ROA3 M= X   = AREA OF ROA3 M 1 + ROA3 M 2- COMMON AREA CROSS ROA3 M   = 60X + 40 X - X^2   TOTAL AREA OF CROSS ROA3 M = 60X+40X-X^2 = 291 M^2   (X-97)(X-3) = 0   X =3   ANSWER 3 M
