Explanation:
This problem bothers on the mensuration of solid shapes, a square shape.
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
![area= length * width](https://img.qammunity.org/2021/formulas/mathematics/high-school/9fg1qu63k2h1w9b9e10gse6w9s4grlgsah.png)
but a square shape has all sides equal hence
![area= length* length\\](https://img.qammunity.org/2021/formulas/mathematics/high-school/vx1ss7q97iudm45yq9ngq6rej5b6k95ejh.png)
![area= l^(2)](https://img.qammunity.org/2021/formulas/mathematics/high-school/3co1gkw3es90d0o4nen1euc1a37ftal5mf.png)
substituting our area and squaring both side to find l we have
![64= l^(2) \\l= √(64) \\l= 8 ft](https://img.qammunity.org/2021/formulas/mathematics/high-school/mndzvw5d3a74de9ktwjxp2vf21xv1qh95c.png)
