90/139 is the only fraction not equivalent to 45/70.
To find if a fractions are equivalent, divide the numerator by the denominator for each fraction.
45/70=0.642857
27/42=0.642857
9/14=0.642857
63/98=0.642857
Notice how all of these get you the same number. However, when you divide 90 by 137, you get 0.64748, which is not the same as the others. Therefore, 90/137 is the fraction that is not equivalent to 45/70.

Answer:
41.24cm²
Step-by-step explanation:
See attachment for the figure
First is to find area of rectangle
Given:
Length of rectangle 'l'= 3cm
breadth of rectangle 'b'= 3cm
Area of rectangle= l x b= 3 x 3=> 9cm²
Next is to find the area of the circle
Given:
radius 'r'= 4cm
Area of circle= πr² => π4² =>50.24cm²
Required:
area of the shaded region=?
area of the shaded region= area of the circle - area of the rectangle
area of the shaded region= 50.24 -9 =>41.24cm²
Therefore, area of the shaded region is 41.24cm²
