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>

Airida [17]

Social Studies rate, S = 30/ 1.5 = 20pages/hr

Novel rate, N = 150/2 = 75pages/hr

Novel rate as a % of Social Studies rate...

N/S × 100% = 75/20 × 100% = 375%

nexus9112 [7]

Answer:

30 sheep

Step-by-step explanation:

Given that the first section has 90 sheep sorted into 3 rows, assuming that each row has equal number of sheep, then the number of sheep per row will be the total number of sheep available divided by the number of rows

= 90/3

= 30

It means there are 30 sheep per row
