Step-by-step explanation:

relative change

, so there is a decrease of
25
%
.
The height is 8 root 3 (sqrt(192)). 8 root 6 = 1/2 * 2 root 2 * x. Simplifying this gives us 8 root 6 = sqrt 2 *x. Square both sides and 64*6=2*x^2 further simplifying gives 192 = x^2, so take the squart root of both sides to get sqrt(192) which is equal to 8 root 3.
