Length of one of the diagonal is 
All the sides of the rhombus are equal
Area of the rhombus with side and one diagonal is
Insert the values
Area with two diagonals length can be given by
Thus, the area of the rhombus is 
and the length of the other diagonal is 
Answer:
s = 1
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 5 , then
sum = 180° × 3 = 540°
sum the interior angles and equate to 540
39s + 129 + 79 + 145 + 148 = 540 , that is
39s + 501 = 540 ( subtract 501 from both sides )
39s = 39 ( divide both sides by 39 )
s = 1
