The area of the given figure (all dimensions are in units) will be
66 sq.units
The area of the figure is the sum of areas of all rectangles and squares contributing to the figure. (4 rectangles and 1 square formed in the centre)
∴ Area = (3 × 4 )+ (3 × 4) + (3 × 4) + (3 × 7) + (3 × 3)
= 12 + 12 + 12 +21 + 9
= 66 sq. units
