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.

Answer 1

Length of the larger rectangle $=1cm\times 9=9cm$
Breadth of the larger rectangle $=1cm\times 9=9cm$
$\therefore$ Area of shaded region = Area of larger square - Area of 41 small Identical square
$=9\times 9-41\times 1\times 1=81-41=40c{m}^2$
