D, you gotta separate the whole into 2 triangles and a square and solve for each individual area
The rectangle area is 98. So if you split it in half, you would get 2 squares. Half of 98 is 49.
If it is now a square, you now simply know, that 7*7=49. Meaning that The sides of the square are 7 each.
7 times the 4 sides equals 28. So the perimeter of one square is 28.
