Question

25. If Å = 3i, B = 4j, A and B are sides of a parallelogram, then area of parallelogram is
a.12 units
b. 7 units
c. j
d. None of these​

Answer 1

Answer: Let   a  and   b   are adjacent sides of a parallelogram

Let   c  be the diagonal of given parallelogram. Therefore, c   =  a  +  b  

 

Now, as we know that,

Area of parallelogram =

a  ×  b  (determinant)

Explanation:

Answer 2

AREA OF A PARALLOLOGRAM=

A×B(DETRAMINE)
