</span><span>the diagonals of a rhombus are perpendicular bisectors of each other
</span>AX<span> = </span>XC<span> = 13. triangle </span>ABX<span> is a right triangle with hypotenuse 14.
</span>
From the pythagoras theorem AB² =<span> AX</span>² + BX²
14² = 13² + BX²
196 = 169 + BX²
27 = BX²----- > BX=√27
BX = 5.20
</span>
The four triangles formed by construction of the diagonals are all congruent since the diagonals are perpendicular bisectors.
Total area of the rhombus is 4 times of ABX triangle
the answer is the option D) 135.1 units ²
