A square also fits the definition of a rectangle (all angles are 90°), and a rhombus (all sides are equal length)

C. 40,320 just did the math right now

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
