Answer:
The length of one side of the blanket is [tex]8ft[/tex]
Step-by-step explanation:
In this problem we are expected to find the side of the square shape.
we know that the area of the square is expressed as
[tex]area= length * width[/tex]
but a square shape has all sides equal hence
[tex]area= length* length\\[/tex]
[tex]area= l^{2}[/tex]
substituting our area and squaring both side to find l we have
[tex]64= l^{2} \\l= \sqrt{64} \\l= 8 ft[/tex]
