Let's look at the formula to solve the perimeter.
2l+2w=98
We know that l=6w
Let's put that into the equation.
2(6w)+2w=98
12w+2w=98
14w=98
98÷14=7
So the width is 7. Let's find the length.
Since the length is six times the width: 7×6= 42
So, the length is 42 while the width is 7. We need to find the area.
42×7=294
The area is 294 m².

Answer:
For the diagram to be a parallelogram, then the measure of x is 4
Step-by-step explanation:
If the diagram is a parallelogram, then the diagonals bisect each other
What this mean is that they divide each other into 2
Mathematically, this means that the values AC is divided into two equal parts AE and CE
That means;
5x + 28 = 3x + 36
5x-3x = 36-28
2x = 8
x = 8/2
x = 4
The slope of -5x + y = 56 is 5
the slope of x + y = -4 is -1
