Answer:
We know that since it's a square, the lenght size is the same on all sides. We can simply use pythagoras theorem:
a^2 + a^2 = 13.5^2
13.5^2 = 182,25
182,25 : 2 (because there are 2 'a') = 91,125
<u>The square root of 91,125 is 9,55 feet.</u>
Answer:
12,014
Step-by-step explanation:
you are adding 12,000 and 14
$26.20 minimum cost of option 1
$36.68 minimum cost of option 2
Area₁ = Length x Width
A₁ = 80 x 36
A₁ = 2880 in² * this in only one side of the door.
Total Area = A₁ x 2 sides = 2880 = 5760 in² * only good for 1 coating of paint
Total Area to be coated = 5760 x 2 coats of paint = 11,520 in²
1st option - $10 / gallon and 4400 sq. in.
2nd option - $ 7 / gallon and 2200 sq. in
11,520 / 4400 = 2.62 x $10 = $26.20 minimum cost of option 1
11,520 / 2200 = 5.24 x $ 7 = $36.68 minimum cost of option 2
1.4 hours cause 560/400 =1.4
