The ratio between the length and the breadth of a rectangular park is 3 : 2. If a man cycling along the boundary of the park at the speed of 12 km/hr completes one round in 8 minutes, then the area of the park (in sq. m) is:  Choose the correct answer
A) 152600m2
B) 153500m2
C) 153600m2
D) 153800m2
E) None of these
Explanation:   Question seems to be typical, but trust me it is too easy to solve, before solving this, lets analyse how we can solve this.   We are having speed and time so we can calculate the distance or perimeter in this question.   Then by applying the formula of perimeter of rectangle we can get value of length and breadth, So finally can get the area. Lets solve it:   Perimeter = Distance travelled in 8 minutes,   =&gt; Perimeter = 12000/60 * 8=

<output>1_600</output>
1600 meter. [because Distance= Speed * Time]   As per question length is 3x and width is 2x   We know perimeter of rectangle is 2(L+B)   So, 2(3x+2x) = 1600   =&gt; x = 160   So Length = 160*3= 
<gadget id="calculator">160*3</gadget>
<output>480</output>
480 meter   and Width= 160*2= 
<gadget id="calculator">160*2</gadget>
<output>320</output>
320 meter   Finally, Area= length * breadth   = 480 * 320= 
<gadget id="calculator">480 * 320</gadget>
<output>153_600</output>
153600   Answer: Option 153600m2
