Divide the trapezium on the other side as well
We will form a rectangle and two triangle with the following measure:
Rectangle
Breadth : 4
Length: 7
Triangles
Breadth : 3
Height: 4
Rectangle
2(l+b)
2(7+4). 2(11)
22
Triangles
1/2(bh)
1/2(3*4)
1/2(12)
6. (Two triangles are there)
6(2)=. 12
Total area
=12+22
34 sq
