Answer:
16u²
Explanation:
It is a regular parallelogram
we have points (3, 4) and (4, 0).
we also have the origin which is (0, 0) and the difference between (0, 0) and (4, 0) on the x axis is 4 and since it is a regular shape, that means the top right corner = (3, 4) + (4, 0), so it is (7, 4). we know the base is 4 now. the vertical height = (7, 4) - (1, 0) which is (6, 4). now we are looking at difference in y. which is between (4, 0) and (6, 4), so the difference is 4.
now we just do 4 x 4 since it is bh and you get 16 units ²
