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
David Livingstone was a Scottish missionary, explorer, and anti-slavery advocate. He embarked upon several missions into Africa, venturing farther into the interior than previous European explorers. While trying to find the source of the Nile River, he became ill in what is now northern Zambia. After his death in 1873, Livingstone’s heart was removed and buried in the African soi
