Answer:
The parallelogram is a square. Perimeter=
[tex]12 \sqrt{2} [/tex]
Area=
[tex]18[/tex]
Step-by-step explanation:
First of all, you have to draw the figure and you will see that is a square. You find the side of the square by using the Pythagorean theorem.
So, l=
[tex] \sqrt{3^{2} + 3 ^{2} } = 3 \sqrt{2} [/tex]
P=
[tex]3 \sqrt{2} \times 4 = 12 \sqrt{2} [/tex]
A=
[tex](3 \sqrt{2} ) ^{2} = 18[/tex]
