Answer:
The answer is option b 130cm²
Area of a trapezium is 1/2(a + b) × h
where 'a' and 'b' are the parallel sides of the trapezium
h is the height
From the picture above
h is 10cm
'a' and 'b' are 17cm and 9 cm respectively
Area of the trapezium = 1/2 ( 17+9)× 10
= 1/2× 26 × 10
= 13 × 10
= 130cm²
