Answer:
Step-by-step explanation:
Width of the room in the drawing = x
1 : 3 :: x : 18
Product of means = Product of extremes
3 * x = 18 *1
x = 18 ÷ 3
x = 6
Width of the room in the drawing = 6 inches
64 - 9 = 55 \sqrt{55} = 7.4161984871
7.4161984871/2 ≈3.7
A=s^2
A=6.3^2
(A=6.3x6.3)
And your answer would be:
A=39.69cm^2
4/1/5=20 because when you divide by a fraction u keep change the divison into multiplaicton and flip the 1/5 to 5/1 so 4x5
