The figure ‘h’ is made up of 9 identical squares
(assume that the figure is evenly-lined) . The total length of the lines needed
to draw the figure is 40 cm. The area of the figure is cm^{ 2}

First we should find out how many sides there are in
the figure. There are 20 sides of the small squares, and the total length of
all the sides is cm, so each side has length 40 ÷ 20 = 2 cm. So the area of
the figure is 2 × 2 × 9 = 36 cm^{ 2}
