The first trapezium is

Area of the trapezium = Area of the rectangle + area of the triangle
Area of the rectangle = length
× width
length = 6m
width = 3m
Hence, area of the rectangle = 6
× 3= 18 sq m
Area of thet triangle =
12 × base
× height
Base = 4m
Height = 3m
Area of the triangle =
12 × 4
× 3
= 6 sq m
Hence, the area of the first trapezium = 18 + 6= 24 sq m
The next trapezium is

Area of the trapezium = Area of the rectangle + area of the triangle
Area of the rectangle = length
× width
length = 5m
width = 4m
Hence, area of the rectangle = 5
× 4= 20 sq m
Area of thet triangle =
12 × base
× height
Base = 4m
Height = 4m
Area of the triangle =
12 × 4
× 4
= 8 sq m
Hence, the area of the first trapezium = 20 + 8= 28 sq m
The next trapezium is
![](https://df0b18phdhzpx.cloudfront.net/ckeditor_assets/pictures/1360539/original_trap_3_s.PNG)
Area of the trapezium = Area of the rectangle + area of the triangle
Area of the rectangle = length
× width
length = 8m
width = 4m
Hence, area of the rectangle = 8
× 4= 32 sq m
Area of thet triangle =
12 base
× height
Base = 4m
Height = 4m
Area of the triangle =
12 × 4
× 4
= 8 sq m
Hence, the area of the first trapezium = 32 + 8= 40 sq m
