Answer:
Step-by-step explanation:
Well.. First of all, the question says that we are working with a rectangle..
So, the rectangle has a length and width. I'll call them L and w.
Look at this phrase: " length that is one foot less than twice its width"
it means, in a algebraic language: L = 2w - 1
Let's analysis the next phrase: "it the area of the rectangle is 91 square feet"
So, A = 91 ft²
But you have to remember that the rectangle area is a product of L and w.
L x w = 91
They are the following equations that you could be used to solve the system of equations.
Now, you have a system of equations and I suggest you to solve it using the substituition method.
L = 2w - 1
L x w = 91
