In order to find the size of the base, count the number of little units of the squared grid that cover the base. that gives you a total of "6"units.
For the height you do the same, but move vertically to cover the full height of the image. In such case you count 5 little squares, and the height is then "5"
Now for the area you use the formula for Area of a parallelogram:
base x height = 6 x 5 = 30 square units.
So please select the:
height 5 units, base 6 units, area 30 square units
option
