Answer:
0.5*13*15 = 97.5 square units
Step-by-step explanation:
If the diagonals of the rhombus are 13 and 15 then its area is 0.5*13*15 = 97.5 square units
Number 8? I don't know which one you are talking about.
When n = 1, 2(1) + 1 = 3
When n = 2, 2(2) + 1 = 5
When n = 3, 2(3) + 1 = 7
When n = 4, 2(4) + 1 = 9
When n = 5, 2(5) + 1 = 11
Sum = 3 + 5 + 7 + 9 + 11 = 35
