GF = 79.8
Explanation:
The shape is divided by parallel lines. This means the ratio of corresponding sides will be applied.
Proportion ratio:
AB/BC = HG/GF
AB = 62ft, BC = 75ft
HG = 66ft, GF = ?
[tex]\frac{62}{75}=\frac{66}{GF}[/tex][tex]\begin{gathered} \text{cross multiply:} \\ GF(62)\text{ = 66(75)} \\ GF(62)\text{ =}4950 \\ GF\text{ = 4950/62} \end{gathered}[/tex][tex]\begin{gathered} GF\text{ = 79.84} \\ To\text{ the nearest tenth, GF = 79.8} \end{gathered}[/tex]
