0.5% error

Step-by-step explanation:

We can use the percentage error formula, which is

.

We know that the approximated value was 8.04, however it is actually 8cm, so we can substitute inside the equation.

1 is b and 2 is d

step-by-step explanation:

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
