Answer:

A

Step-by-step explanation:

The diagonals of a parallelogram bisect each other. Hence, the two shorter sides created on diagonal RT ("6x-7" and "x+28" ) are equal.

<em>We can set them equal and solve for x:</em>

<em>6x-7=x+28\\6x-x=28+7\\5x=35\\x=\frac{35}{5}\\x=7</em>

<em />

<em>So the side length of 6x -7 is:</em>

<em>6(7)-7 = 35</em>

<em>and the side length of x + 28 is:</em>

<em>7 + 28 = 35</em>

<em />

<em>THus, the diagonal RT = 35 + 35 = 70 units</em>

<em />

<em>Answer choice A is right.</em>
