The area of a triangle is given by the following formula:
[tex]A=\frac{1}{2}b\times h[/tex]Where "b" is the base and "h" is the height. From this formula, we can solve for h to get:
[tex]\begin{gathered} \frac{2A}{h}=b \\ b=\frac{2A}{h} \end{gathered}[/tex]From the statement of the question, we know that A equals 6ft^2 and h equals 4 ft. By replacing these values into the above formula, we get:
[tex]b=\frac{2(6)}{4}=\frac{12}{4}=3[/tex]Then, the length of the base of the triangular flag equals 3 ft
