Question

The diagonals of a parallelogram are 2i and 2j, what is its area

Answer 1

Final Answer : 2units

Understanding:
1) Vectors

Steps:
1) The area of a parallelogram having Diagonals as D1 and D2 vector, then there area is given by
1/2 |(D1 x D2)|

Here, D 1 = 2i
D2 = 2j

Therefore,
Area = 1/2 |(2i x 2j) |
=1/2 * 4
= 2 units.

Answer 2

Answer:

4 units

Step-by-step explanation:

Area=|2i*2j| = |4k| =
