Question

Find the value of $xy$, if $ABCD$ is a parallelogram.

• A. 6
• B. 8
• C. 9
• D. 12

Answer 1

The correct option is D 12

Given ABCD is parallelogram.

So, AD = BC (Opposite sides of a parallelogram are equal)

$\therefore 2y+4=12$

$⟹y=4$


Similarly, AB = DC (Opposite sides of a parallelogram are equal)
$\therefore 5x+3=18$

$⟹x=3$

Hence,
$xy=3\times 4=12$
