Step-by-step explanation:
It would be 400. 399 rounds up to 0 making it 400 and the 2 rounds down to 0. making it 400
Check the picture below.
so as you already know, a rhombus is a parallelogram whose sides are equal, so the distance from say (-10, 1) to either endpoint of the other diagonal must be the same.
