Answer:
8.51 cm
Step-by-step explanation:
Since their diagonal lines are equal, let's find the rectangle diagonal size
from the pythagorus' theorem we know that
diagonal ^2 = 12 ^2 + 0.8 ^2
=64(1.5 ^ 2 + 0.1 ^ 2)
=64root(2.26)
##diagonal = 8 * (2.26) ^ (1/4) around 12.027
Since a square has a diagonal of 12.027 we now know that it's side is 12.027 / root(2) around 8.51
