Question 1: Find the area of the following figure :
Divide the figure into three parts as shown
Fig i : Figure I is a square of side 2 m.
So, area of figure I = (2 × 2) m^{2 }= 4 m^{2}
Fig ii : Figure II is a rectangle whose length is
2 m + 2 m + 2 m = 6 m and
breadth = 2 m.
So, area of figure II = (6 × 2) m^{2} = 12 m^{2}
Fig iii : Figure III is a square of side 2 m.
So, area of figure III = (2 × 2) m^{2} = 4 m^{2}
Hence, area of the given figure = 4 m^{2} + 12 m^{2} + 4 m^{2} = 20 m^{2}
Question 2: Find the area of the triangle shown on the graph paper.
Number of complete squares (1 to 23) enclosed by the figure = 23
Number of more than half squares (marked as 7) enclosed by the figure = 4.
Number of halfsquares (marked as 3) enclosed by the figure = 6
Hence, area of the triangle = (23 + 4 + 1/2 + 6) sq. cm = 30 sq cm
