Answer:
510.84 ft²
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>
= 4( 12.9ft x 9.9ft)
= 4 (127.71 ft²)
= 510.84 ft²
So area Alyssa will paint = 510.84 ft²
<em>(assuming she will paint only wall s of her room not the ceiling)</em>

The coordinates of the endpoints of the midsegment for △LMN that is parallel to LN are (3, 4.5) and (3, 3).
Explanation:
Given that △LMN
We need to determine the coordinates of the endpoints of the midsegment for △LMN that is parallel to LN
The midsegment of the triangle parallel to side LN is the midsegment connecting the midpoint of side LM and the midpoint of side MN.
The midpoint of LM is given by

Simplifying, we get,

The midpoint of MN is given by

Thus, the coordinates of the endpoints of the midsegment for △LMN that is parallel to LN are (3, 4.5) and (3, 3).
