Answer:

Step-by-step explanation:
we know that
The sides of a rhombus are all congruent and the diagonals are perpendicular bisectors of each other
so
Applying the Pythagorean Theorem

where
c is the length side of the rhombus
a and b are the semi-diagonals
we have

substitute the values



To find out the perimeter of the rhombus multiply the length side by 4

Answer:
B $17.00
Step-by-step explanation:
8 batteries are 13.60
6.80 split in half to become 2 is 3.40 and then I added 13.60 plus 3.40 to get 17.00
Without needing the distance formula
from 4,1 to 0,1, you move the "x" from 4 to 0, over the same "y" value of 1, so is just 4 units long, from the center to an endpoint, and the chord that stems from the center to an endpoint is the radius, so r = 4
