QUAD is a rhombus. If QR=21 , RD=20, what is the length of QD?
WITCHER [35]

Answer:

Correct answer:  QD = 29

Step-by-step explanation:

Given:

QR = 21  half the longer diagonal

RD = 20  half shorter diagonal

QD = ?   rhombus side

The diagonals of the rhombus are known to be perpendicular to each other.

We will calculate the side of the rhombus using Pythagorean theorem.

QD² = QR² + RD²

QD² = 21² + 20² = 441 + 400 = 841

QD = √841 = 29

QD = 29
