<u><em>C. 20√15 is the correct answer.</em></u>  First you had to multiply by the numbers, and it gave us, 5*4=20, and 20\sqrt{5} \sqrt{3}. Then you had to used apply radical rule, and it gave us, \sqrt{5} \sqrt{3}=\sqrt{5*3}, and =20\sqrt{5*3}. And finally multiply by the numbers, and it gave us the answer is 5*3=15, and  <u><em>20√ 15 is the final answer.</em></u> You can also round up to the nearest hundredths is 77.45 to 77.50. Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie

The area of the house is the amount of space on the house.

  • The length of the addition is x + 20
  • The area of the original house is x^2 + 30x + 200

<h3>The length of the addition</h3>

The area of the addition is given as:

Area = x^2 + 10x - 200

Expand

Area = x^2 + 20x - 10x - 200

Factorize

Area = x(x + 20) - 10(x + 20)

Factor out x + 20

Area = (x -10)(x + 20)

The width of the addition is x - 10.

Hence, the length of the addition is x + 20

<h3>The area of the original house</h3>

The dimension of the original house is

x + 20 by x + 10

So, the area is:

Area =(x + 20)(x + 10)

Expand

Area =x^2 + 20x + 10x + 200

This gives

Area =x^2 + 30x + 200

Hence, the area of the original house is x^2 + 30x + 200

Answer:

452.16 m³

Step-by-step explanation:

d = 3h = 3×4m = 12 m

r = d/2 = 12m/2 = 6 m

V = Ab×h = π·r²·h

= 3.14×36m²×4m

= 452.16 m³
