Answer:
[tex] \displaystyle A_{ \text{triangle}} = 102 {m}^{2} [/tex]
Step-by-step explanation:
remember that,
[tex] \displaystyle A_{ \text{triangle}} = \frac{1}{2} bh[/tex]
given that,b is 17 m and h is 12m
thus substitute:
[tex] \displaystyle A_{ \text{triangle}} = \frac{1}{2} \times 17\times 12[/tex]
reduce fraction:
[tex] \displaystyle A_{ \text{triangle}} = 17\times 6[/tex]
simplify multiplication:
[tex] \displaystyle A_{ \text{triangle}} = 102 {m}^{2} [/tex]
