Answer:
The area of Trapezium is 21 cm²
Step-by-step explanation:
Divide the trapezium into a Triangle and Rectangle.
The length of the side is given in the figure behind.
So,
The area of Trapezium
= The area of Triangle + The area of Rectangle
= 1/2 × 4 × 3 + 5 × 3 cm
= 6 + 15 cm
= 21 cm²
Thus, The area of Trapezium is 21 cm²
