I’m hoping this helps (but hopefully now you can give the brainliest to the person above)
I’m not very familiar with the square roots method but I believe you try and isolate the term that is squared.
Lets name the shortest piece a, the medium b and the longest c
Together they are 90inches

The longest is 30 inches longer than the shortest

The third piece is half the lenght of the longest

So if you place c=a+30 in the other 2 equasions you get

And

Now if you put this 2 toghether u get

Multyplied by 2


Meaning that a=18inches
Now that we have the lenght of a we put it in the previous equasion

So b=48/2 which means b=24inches
And together they must be 90 so

C=48inches
