Find the area of the following figures.
Each square stand for 1 square unit and each triangle stands for a half square unit.
Problem 1 :
Solution :
Total number of square = 4
Area of complete squares
= number of squares x area of each square
= 4 × 1
Area of squares = 4
Total number of triangles = 4
Area of triangles = 4 × 0.5
= 2
Required area = 4 + 2
= 6 square units
Problem 2 :
Solution :
By observing the figure,
Total number of square = 6
= 6 × 1
= 6
Total number of triangle = 4
= 4 × 0.5
= 2
Required area = 6 + 2
= 8 square units
Problem 3 :
Solution :
Total number
of square = 6
Area of squares = 6 × 1 ==> 6
Total number of triangle = 2
Area of triangles = 2 × 0.5 ==> 1
Area of the shaded portion = 6 + 1
= 7 square units
Problem 4 :
Solution :
Total number
of square = 12
Area of shaded squares = 12 × 1 ==> 12
Total number of triangle = 4
Area of shaded triangles = 4 × 0.5 ==> = 2
Total number of area = 12 + 2
= 14 square units
Problem 5 :
Solution :
Total number
of square = 6
Area of squares = 6 × 1 ==> 6
Total number of triangle = 2
Area of triangles = 2 × 0.5 ==> 1
Area of shaded portion = 6 + 1
= 7 square units
Problem 6 :
Solution :
Total number
of square = 6
Area of shaded squares = 6 × 1 ==> 6
Total number of triangle = 2
Area of shaded triangles = 2 × 0.5 ==> 1
Required area = 6 + 1
= 7 square units
Problem 7 :
Solution :
Total number
of square = 4
Area of shaded squares = 4 × 1 ==> 4
Total number of triangle = 8
Area of shaded triangles = 8 × 0.5 ==> 4
Required area = 4 + 4
= 8 square units
Problem 8 :
Solution :
Total number
of square = 6
Area of shaded squares = 6 × 1 ==> 6
Total number of triangle = 4
Area of shaded triangles = 4 × 0.5 ==> 2
Required area = 6 + 2
= 8 square units
Problem 9 :
Solution :
By observing the figure,
Total number of square = 8
Area of shaded squares = 8 × 1 ==> 8
Total number of triangle = 6
Area of shaded triangles = 6 × 0.5 ==> 3
Required area = 8 + 3
= 11 sq.units
