Answer:
Step-by-step explanation:
<u>Heron's Area formula:</u>
- A =
, where s is semi-perimeter - s = 1/2(a + b + c)
We are given two sides and the included angle.
<u>Use the law of cosines to find the missing side:</u>
- a² = b² + c² - 2bccos A
- a² = 77² + 41² - 2*77*41*cos 79
- a² = 6405
- a = 80 (rounded)
<u>Now find the value of s:</u>
- s = 1/2(80 + 77 + 41) = 99
<u>Find the area:</u>
- A =
= 
= 1549.24

Answer:
The formula to determine the area covered by one can of paint is 
Step-by-step explanation:
The formula that describes this scenario , 6=w/p
where
w is the total area of the walls
p is area covered by a can of paint
The formula says that to paint the total area we need 6 can of paints
Thus to with the one paint can the area that can be covered is
