Given one side of the garden is x feet long.
So, let's assume length = x
He plans to use 120 feet of fencing. Fencing means the perimeterof the rectangle.
So, p = 120
2 *length + 2* width = 120
2x + 2 *width = 120
2x + 2* width - 2x = 120 -2x Subtract 2x from each sides of the equation.
2* width = 120 - 2x
Width = 60 - x Divide each sides by 2 to isolate width.
Now area of the rectangle will be:
Area = Length * width
= x * (60-x)
So, the model to find the area of the rectangle is x(60 -x) square feet.
Hope this helps you!
If the sum of the square of a number plus the triple of the same number equals eighteen, the required numbers are 3 and -6
Let the unknown number be x
The square of the number is expressed as x²
Triple of the unknown number will also be expressed as 3x
Taking the sum of both numbers and equating it to 18 will give;
Factorize the resulting equation:
Hence the required numbers are 3 and -6
