Answer 2

Answer:

$rs. \: 6 \sqrt{130}$

Step-by-step explanation:

By herons formula the area of triangle is:-

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

$\sqrt{27(27 - 15)(27 - 25)(27 - 12)}$

$\sqrt{27 \times 15 \times 2 \times 13}$

$3 \sqrt{130 \: sq \: cm}$

Therefore, the cost of painting

$2 \times 3 \sqrt{130}$

$= rs.6 \sqrt{130}$
