2. A cylindrical jar is of height 12cm and has diameter 5 cm. Find the lenght of the longest stick which can fit in the jar.



Answer 1-
there is a formula for finding the total sum of all interior angles.
it is (n-2)*180..... n are the no. of sides
here there are 4 sides so the total sum of all interior angles will be 360
the ratio is given m:n:o:p as 2:2:1:1 
so we will write it as 2x + 2x +1x+1x=360
now that we know the value of x, we can find values of angles easily. 
we get,
<o=60 degree
<p=60 degree
 so according to the answer, the quadrilateral formed is a trapezium.
