If a rectangle is divided into four parts of different size of rectangles. Area of the 1st part is 76, area of 2nd part is 4, area of 3rd part is 8. Then find out the area of fourth part of the rectangle.

• let area of 4th part is X then
  if part 1,2,3,4 are in clockwise then
  
  76/x = 4/8
  => x = 152

• 76=19*4
  4=1*4
  8=2*4
  so width of rectangle is 4
  let the length of the 4th part is x
  then total area of recatngle is (22+x)*4
  
  76+4+8+4x=88+4X
  x=1
  so area fourth part is 4x=4*1=4
  ans:4

• 76=38*2,
  8=4*2,
  4=4*1,
  if we divide the rectangle frst part area 76,beside it second part area 8,down of second part wil be the third part area 4.
  we can obtain fourth part parameters as length=38,breadth=1
  hence fourth part area will be 38*1=38

• first ractangle is of 76 (let 19*4) similarly in contineous way second ractangle is of 8 (i.e 4*2)
  for third 4 (only possible ractangle is 4*1) hence if we draw thethree ractangle then only possible values for last ractangle is 15*1 i.e 15
  Ans:15

• 1st part area = 76=19*4 (l1=19,b1=4)
  2nd part= 4= 2*2 (l2=2, b2=2)
  3rd part= 8= 4*2 (l3=2,b3=4)
  4th part area would be = 19 *2= 38
