Step-by-step explanation:
Given that,
dimensions of wall = 12.9ft by 9.9ft
height of wall = 12.9ft
width of wall = 9.9ft
there are total 4 walls in a bedroom to be painted blue.
Formula to calculate area of one wall
<h3>Height x Width</h3>
Formula to calculate area of four walls
<h3>4 (Height x Width)</h3>
