The line is 7 units long. Add the two equations together and set equal to 7:
7x-1 + 2x-1 = 7
Combine like terms:
9x-2= 7
Add 2 to both sides:
9x= 9
Divide both sides by 9:
X= 1
Answer:
The length of the side of the original garden is 5 m.
Step-by-step explanation:
Let the original side of the garden be x.
SInce we are given that the side is incresed by 7 m.
So, the new side = x+7
Formula of area of square =
Where x is the side length of square .
So, area of garden after increasing the length of side by 7 =
Since we are given that the new total area of the garden will be
⇒
⇒
⇒
⇒
⇒
Thus the length of the side of the original garden is 5 m.
