Question

the area of a parallelogram is 48cm².if the two adjacent sides are 8cm and 6cm, find the length of its diagonal .​

Answer 1

Answer:

10cm

Step-by-step explanation:

Assuming the shape is a rectangle since it's already stated that it's a parallelogram, and the area is stated, we can use the Pythagorean theorem to find the length

$a^{2} +b^2=c^2$, where c will be the length

isolate c

$c^2=a^2+b^2$

$c=\sqrt{a^2+b^2}$

substitute for a and b

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

$c=\sqrt{64+36}$

$c=\sqrt{100}$

$c=10$
