Answer:
Rhombus Property- all sides are equal
so AB=CD
Explanation:
( 7x + 3) = ( 2x + 38)
7x- 2x = 38 - 3 Transpose variables to one side.
5x = 35
x = 35/5
x = 7
Check
( 7x + 3) =7 x 7 + 3 = 52
( 2x + 38) = 2x 7 + 38 = 52
Correct
To find the side of the rhombus
52 = 2 side so,
52/2 = 26 = 1 side 26 mm to cm divide by 1000
so,0.026mm
Perimeter= 0.104
