View full question & answer→Total area
$= 2 \times$ Area of asbestos $+ 2\ x$ Area of wall $+ 2\times (6)^{\circ}\text{AE} \times$ length
$= 500 + 2 \times 72 + 2 \times 7.5 \times 50 ...($from $a$ and $b)$
$= 500 + 144 + 750$
$= 1394\ m^2$
$\therefore$ The total surface area of the shed is $1394\ m^2.$
