SOMEONE HELP AS SOON AS POSSIBLE please:))

This is an isosceles triangle which means two of the side lengths are equal. Those are the given side and the side labelled y
Therefore y = [8 (root 3)] / 3

Using Pythagorean Theorem we know
x^2 = a^2 + b^2
x = (root 384) / 9
x = [ 8 (root 6) ] / 9

A=bxh3.2x1.8=5.76 centimeters square
