Answer 1

Step-by-step explanation:

$1 = 2 = s = \frac{a + b + c}{2}$

$s = \frac{5 + 5 + 4}{2}$

$s = \frac{14}{2} = 7 \: cm$

$area \: = \sqrt{s(s - a} )(s - b)(s - c)$

$\sqrt{7(7 - 5)} (7 - 5)(7 - 4)$

$\sqrt{7 \times 2 \times 2 \times 3}$

$\sqrt{84} = 2 \sqrt{21} = 4.58 \times 2 = 916$

$3 = 4 = \frac{8 + 8 + 3}{2} = \frac{19}{2} = 8.5$

$\sqrt{8.5(8.5 - 8)} (8.5 - 8)(8.5 - 3)$

$\sqrt{} 8.5 \times 0.5 \times 0.5 \times 5.5$

${11.68} = 23.37$

$5 = \frac{1}{2} \times 3 + 4 \times 1$

$\frac{1}{2} \times 7 \times 1$

$\frac{1}{2} \times 7 = 3.5$

$total \: side \: = \\ 9.16 + 23.37 + 3.5 = 36.03 \: (approx.)$
