69 cm²

Step-by-step explanation:

To find the area. of this whole diagram ,

first find the area of the triangle And then trapezium . and then add the area of both .

Here ,

area of triangle :-

base = 6 cm

height = 8cm

area = 1/2 × product of base and height

=> 1/2 × 8 × 6

=> 4 × 6

=> 24 cm²

area of trapezium :-

height = (13 - 8 ) cm = 5 cm

base = 12 cm

area = 1/2 × (sum of base and its parallel base ) × height

=> 1/2 × (12+6) × 5

=> 1/2 × 18 × 5

=> 9 × 5

=> 45 cm²

Area = (area of triangle + area of trapezium)

=> (24 + 45) cm²

=> 69 cm²
