Total length = 111.6 metres
(12.3x7) + 15 + 10.5 = total length
Answer:
<em>A ≈ 28.5</em>
Step-by-step explanation:
a, b, c
P = a + b + c
Semiperimeter s =
A =
~~~~~~~~~~~~~~~
= 4.3 + 2.89 + 6.81 = 14
s = 14 ÷ 2 = 7
= = √14.75901 ≈ 3.84
= 8.59 + 7.58 + 6.81 = 22.98
s = 22.98 ÷ 2 = 11.49
= = √609.7343148 ≈ 24.6928
= 3.84 + 24.6928 ≈ <em>28.5</em>
