Answer 2

Area of door = Length × Breadth

= 3 m × 2 m

$\: \: \: \: \: \: \: = 6 \: m {}^{2}$

Area of wall including door = Length × Breadth

= 10 m × 10 m

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 100 \: m {}^{2}$

Area of wall excluding door = 100 - 6

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 94 \: m \: {}^{2}$

Total labour charges for painting the wall is = 2.50 × 94

= Rs. 235
