Answer:
The answer is 2940ft^2
Step-by-step explanation
First convert length and width to feet using the value given (7ft=1inch).

Multiply these values for the actual area.

The actual area of the lawn is 2940ft^2
- The system of equations has infinite many solutions.
- The y-intercepts of the equations are -8
- The slope for the Rover A equation is 1.9 and slope for the Rover B equation is 1.9
Step-by-step explanation:
Given equations are:
Rover A: y= 1.9x – 8
Rover B: 7y= 13.3x - 56
simplifying the second equation

Dividing both sides by 7

As we can see that both equations are equivalent
Slope-intercept form is :

Comparing both equations with slope-intercept form we get
Slope of Rover A = 1.9
Slope of Rover B = 1.9
y-intercepts = -8
As both equations are equivalent, the system will have infinite many solutions.
Hence,
- The slope for the Rover A equation is 1.9 and slope for the Rover B equation is 1.9
- The y-intercepts of the equations are -8
- The system of equations has infinite many solutions.
