Answer:(-1,-2)
Step-by-step explanation:
The total area with land based on the information given is 3x² + 60x.
<h3>How to find the area?</h3>
Let the width = x
Let the length = (1.5 × x) = 1.5x
Area = 1.5x × x = 1.5x²
The area along with land:
Width = x + 20
Length = 3 × x = 3x
The total area with land:
= Length × Width
= 3x(x + 20)
= 3x² + 60x.
