Example 2. . We want to find the area of the shaded part. A = l × w where l is the length,
where l =
26cm , w = 10cm
diameter of the circle = 5 cm, radius = ½ of 5 = 2.5cm Area of the circle = 3.142
× 2.5 × 2.5 Area of the rectangle = 26 × 10 cm^{2} Area of the shaded part = Area of the rectangle  Area of the circle



To find the area of the figure, first we need to identify the shapes. Fig.(a) rectangle Fig.(b) triangle Then we have to use the formula to calculate the area of each shape. Rectangle: A = l × w where l is the length, w is the width, A is the area. where l = 10units , w = 6units Triangle: A = ½ b ×h where b is the base length, h is the height, A is the area. where b= 10 units, h= 6 units Substitute the values and calculate the areas and add them together to find the total area. 
Solution 2

Identify the shapes. Fig.(a) ~ rectangle Fig.(b) ~ semicirle Use the formulae to calculate the areas. Rectangle: A = l × w where l is the length, w is the width, A is the area. Area of a Circle: Area of the semi circle = area of the circle ÷ 2
