Hey guys please help ​
zimovet [89]

Answer:

7.98 \:m

Step-by-step explanation:

Area of a triangle is base times height divided by 2.

A= \frac{bh}{2}

69.6= \frac{b \times 17.45}{2}

69.6 \times 2= b \times 17.45

139.2=b \times 17.45

\frac{17.45b}{17.45}=\frac{139.2}{17.45}

b=\frac{2784}{349}

b=7.97707

The appropriate unit is meters.
