Question 124
Calculate the area of shaded region in the given figure, where all of the short line segments are at right angles to each other and 1 cm long.
Length of the larger rectangle =1 cm×9=9 cm
Breadth of the larger rectangle =1 cm×9=9 cm
∴ Area of shaded region = Area of larger square - Area of 41 small Identical square
=9×9−41×1×1=81−41=40 cm2
