Substitute 2 into x in the equation so f(x)= 5x2 -12 = -2 so it’s C = -2
Given :
Perimeter of rectangular filed , P = 316 yards.
The length of the field is 4 yards less than twice its width.
To Find :
The dimensions of the playing field.
Solution :
Let, width be x.
So, by given condition length will be 2x - 4.
Perimeter is given by :
P = 2( l + b )
316 = 2( 2x - 4 + x )
3x - 4 = 158
x = 54 yards.
So, the dimensions are 54 yards and 104.
Hence, this is the required solution.
