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

Answer : one of the factor is (2h+1)

LEts factor the given expression
WE have negative in common
so we factor out negative

Now we multiply 2 and 7 = 14
We find out two factors whose product is 14 and sum is 15
1 times 14 = 14
1 + 14 = 15
So two factors are 1 and 14
Now split the middle term 15h using factors 1 and 14

We group first two terms and last two terms and factor out GCF



So one of the factor is (2h+1)
