Const. Draw line he, ef, fg and gh Draw the line hf parallel to ab and de Such that ab is parallel to hf is parallel to de So abfh and defh are the parallelograms Now in parallelogram abfh Trialngle efh and parallelogram abfh are on the same base and between the same parallels. So triangle efh is 1/2 of parallelogram abfh (by mid point theo.)........~1 Similarly, area of triangle gfh= 1/2 area parallelogram edhf (mid point theo.)........~2 Now adding eqn.1 and 2 we get, Area ofParallelogram efgh=1/2 area of parallelogram abcd

What is irrational no. ?

Yogita Ingle 5 years, 8 months ago

5/7=0.7142 9/11=0.818181
first we have to change the the number into decimal or rational
decimal form of 5/7 is 0.71428571 and the decimal form of 9/11 is 81818181
hence the rational number are between 0.71428571 and 0.81818181

rational numbers between 5/7 and 9/11
1) 0.72428571
2)0.73428571
3)0.74428571
      .
      .
      .
      .
upto 0.80818181
you can take any number between them as irrational.
