Answer 1

Answer:

You should write full question !!!

What is the rate of per m^2 ?

Anyway Here is you explanation

Area of Door = 3.5m × 1.5 = 5.25^2

Area of wall with door = 12m × 5.5m = 66m^2

Here we have to paint wall only , So we have to subtract Area of door from the Area of wall

= 66m^2 - 5.25m^2 = 60.75m^2

Area of wall alone = 60.75m^2

Now ,

Cost of painting wall per m^2 = x ( put value here )

Cost of painting wall 60.75m^2 = 60.75m^2 × x = ANSWER ( write the answer here after multiplying the value of x )
