The side of inside square is of 2 units.
The length of prependicular from the vertex of triangle to side of square is 1 unit.
So right triangle is obtained as,
Determine the length of side AB by using pythagoras theorem.
[tex]\begin{gathered} AB=\sqrt[]{(1)^2+(1)^2} \\ =\sqrt[]{2} \\ =1.414 \\ \approx1.4 \end{gathered}[/tex]
So sides of each triangle are 1.4 foot, 1.4 foot and 2 foot.
The side of inside square is of 2 foot.
