Question

1. rt = 19.8 find rp

Explanation:

Step1: Recall property of rectangle

In a rectangle, the diagonals are equal and bisect each other. So $RP = SQ$ and $RT=\frac{1}{2}RP$.

Step2: Calculate RP

Since $RT = 19.8$ and $RT=\frac{1}{2}RP$, then $RP = 2\times RT$.
$RP=2\times19.8 = 39.6$

Answer:

$39.6$
