The answer is 9 because if you find the two side lengths and find the area of the square then divide it by 2 it equals 9
9 I think because 1/4 needs to have 4 of those to be a whole so yeah 9.
The correct answer is 30cm
Jjjsjjajjsjjsjdjdj answer is 2790
We have x = 4 repeating itself
If we graph the two points (4,1) and (4,20), then we see the relation fails the vertical line test.
The input x = 4 leads to more than one output y = 1 and y = 20 simultaneously.
This is why we don't have a function.
