Answer: Width = 6 meters
Length = 10 meters
Explanation:
Here's the complete question:
A room has an area of 60 square meters and a perimeter of 32 meters. What are the length and width of the room?
Area = Length × Width
Perimeter = 2(Length + Width)
Therefore,
L × W = 60 ....... i
2L + 2W = 32 ....... ii
From equation ii,
2L + 2W = 32
Divide through by 2
L + W = 16
L = 16 - W ........ iii
Put the value of L into equation i
L × W = 60
(16 - W) × W = 60
16W - W² = 60
W² - 16W + 60 = 0
W² - 10W - 6W + 60 = 0
W(W - 10) - 6(W - 10) = 0
(W - 6)(W - 10) = 0
Therefore,
W - 6 = 0
W = 0 + 6
W = 6
Width = 6 meters
Since Length = Area / Width
Length = 60/6
Length = 10 meters
Answer to this is Jefferson Davis
Answer: Royal court spent too much. France was too indepted. France supported American independence against the British (also expensive) and lost its colony New France (Treaty of Paris, 1763). Immediately before the revolution poverty was extreme because of the climate (harsh winter).
Explanation: There were many external factors that worsened condition of common people in France (the Third state).
The correct answer is B. It significantly reduced the cost of producing steel, making the material more available for building machinery, railroads and skyscrapers.
The Bessemer process was named after its English inventor Henry Bessemer, who invented it in 1856. Its many advantages over the older processes of steel fabrication included:
- Faster fabrication: to convert five tons of iron into steel usually took a full day whereas it took 10 to 20 minutes.
- Better Steel quality: oxidation is used to remove impurities from the steel which in turn is much stronger.
