Answer:

510.84 ft²

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

Height x Width

Formula to calculate area of four walls

4 (Height x Width)

= 4( 12.9ft x 9.9ft)

= 4 (127.71 ft²)

= 510.84 ft²

So area Alyssa will paint = 510.84 ft²

(assuming she will paint only wall s of her room not the ceiling)
