Answer:
20 (units)
Step-by-step explanation:
If the diagonals in a rhombus are 8 and 6 then the perimeter is
a) 16
b) 18
c) 20
d) 22
the regular rhombus is formed by 4 right triangles, 1/2 of the diagonal is the cathetus.
8 : 2 = 4
6 : 2 = 3
find with Pythagoras the side of the rhombus
s = √(4² + 3²)
s = √(16 + 9)
s = √25
s = 5
now we find the perimeter by adding the 4 sides
5 + 5 + 5 + 5 = 20
