Answer 2

Explanation:

Complete step-by-step answer:

We have the dimensions of the wall and the dimensions of the door-frame. Let us first find out the area of the wall which needs to be painted.

Area of the wall = length of the wall × breadth of the wall

= 10 × 10

=100m2

Now, here we have the area of the wall as 100 sq. meters.

Further, now let us calculate the area of the door-frame which occupies 3m × 2m of the space on the wall.

Area of the door frame = length of the door-frame × breadth of the door-frame

= 3×2

= 6m2

Here, we have the area of the door frame as 6 sq. meters.

Now to find the area which needs to be painted, subtract the area of the door-frame from the area of the wall.

Area which needs to be painted = Area of the wall – Area of the door-frame

= 100 – 6

= 94

Therefore, we found out that the area which needs to be painted is 94m2.

Now, the next step is to find the total labour charges required for painting the wall. Here, we have the labour charges for painting 1m2 is Rs. 2.50.

Therefore, let us find the labour charges to paint 94m2. Let us consider the total labour charges for painting the wall as ‘x’.

1 = 2.50

94 = x

x = 94×2.50

= 235

Hence, the total labour charges for painting the wall is Rs. 235.

Note: Here, in this question if you notice the dimensions of the wall, it has 10m × 10m which states that both the measurements are the same. So, the wall is in square shape, although either formula, area of rectangle = l × b or area of square = s2can be used to find its value.
