Remember that

the area of a triangle is equal to

[tex]A=\frac{1}{2}\cdot b\cdot h[/tex]

we have

A=10.98 ft2

h=3.6 ft

substitute the given values

[tex]\begin{gathered} 10.98=\frac{1}{2}\cdot b\cdot3.6 \\ \\ b=\frac{10.98\cdot2}{3.6} \\ \\ b=6.1\text{ ft} \end{gathered}[/tex]

answer is 6.1 ft
