Answer:

Step-by-step explanation:
Let, the length of the rectangle be 'L'
and, width of the rectangle be 'W'
length=2*Width+3

Area of the rectangle= 90 square feet
Area of a rectangle = Length*Width

Using Factorization Method to solve quadratic equation:

Taking common from the equation:

OR

The Width cannot be negative, therefore Width(W)=12 feet


Swapping rows alters the sign of the determinant:

Multiplying a single row by a scalar scales the determinant by the same amount:

Then
