Question

We know that parallelogram is also a quadrilateral. Let us
also split such a quadrilateral into two triangles, find their
areas and hence that of the parallelogram. Does this agree
with the formula that you know already? (fig 11.12 ) .​

Answer 1

Answer:

area of two triangle is= 2 X 1/2X b X h

=2/2 X b X h

=1 X b X h

= b X h

area of parallelogram= area of 2 triangle= b X h

Yes it agree with the formula that we know earlier that area of parallelogram is b X h

Answer 2

Step-by-step explanation:

area of two triangle is=2 X 1/2X b Xh

2/2 X bXh

1XbXh

= bXh

area of parallelogram= area of 2 triangle=

bXh

Yes it agree with the formula that wee know earlier that area of parallelogram is bXh
