Answer:
Step-by-step explanation:
a₁₂ = a₅ + (12-5)d
72 = 23 + 7d
d = 7
a₃ = a₅ + (3-5)d = 23 - 2⋅7 = 9
a₂ = a₃ - d = 9-7 = 2
a₁ = a₂ - d = 2 -7 = -5
Answer:
18 units
Step-by-step explanation:
Let the diagonals be x:y=3:2
From this , we have:
The area of a rhombus, is given by:
This means:
This is equal to 108 as given in the question.
We substitute to get:
This means:
The longest diagonal is 18
It's 0.19569472. Or to the 4th decimal place, 0.1957
