$\triangle WYZ$ is equilateral  and $\triangle WXY$ is isosceles with a vertex angle of $\angle XWY.$ If the perimeter of the entire figure is $22$ units and the area of the entire figure is $9 \sqrt{3}  + 4 \sqrt{5},$ what are the side lengths of each side of each triangle?

Is it not  4sqrt(9)??coollaugh that would work like a charm

the sides would be  5,5,6  and  6,6,6

4 sqrt 9 for what?

Because it asks for side lengths

No, 4 sqrt 5 is correct.
