Question

ABCD is a Rhombus. AC=8 centimeters, BD =6 centimeters what is the perimeter of ABCD?

• A. 28 centimeters
• B. 20centimeters
• C. 24centimeters
• D. 14centimeters

Answer 1

Answer:

B. 20centimeters

Perimeter=$2\sqrt{p^2+q^2}$

$p = 8cm, q = 6cm$

Perimeter $=2\sqrt{8^2+6^2}$

$=2\sqrt{64+36}$

$=2\sqrt{100}$

$=2\times10$

$= 20$
