Answer:
A
Step-by-step explanation:
The diagonals of a rectangle are congruent and bisect each other, so
AC = BD
2AG = 2DG, that is
AG = DG, substitute values
- 7y + 5 = 2y + 68 ( subtract 2y from both sides )
- 9y + 5 = 68 ( subtract 5 from both sides )
-9y = 63 ( divide both sides by - 9 )
y = - 7
Hence
BD = 2(2y + 68)
= 4y + 136
= (4 × - 7) + 136
= - 28 + 136
= 108 → A
