Answer:
Let 'x' be one side of the rectangular lot
'y' be the other side
Perimeter:
P = 2x + 2y
2x + 2y = 90
Area:
A = xy
xy = 450
Since the product of the roots is defined by:
x1 × x2 =
and sum of the roots is
where A is the coefficient for x², B for x and C is the constant.
Using the equations above, we will know that the product of the roots or in that case is the dimensions of the lot is represented by the equations:
2x + 2y = 90 and xy = 450
or reducing the first equation to lowest term by dividing the whole equation by '2' we'll have x + y = 45
dividing the sum and product of the roots, we'll have
So we'll have B = -45 and C = 450
Considering the equation we'll have:
Ax² + Bx + C = 0
then we'll divide the equation with A since we don't know its coefficient:
solving for x:
and those are already the dimensions..
Since the standard is that the length is of bigger value than that of the width then considering that common knowledge, you'll have length as 30 and width as 15
