4. use the scale to find the actual length of the elephant: see image below

the scale is 0.25 in is 2 feet

The length of the elephant in the scale is 1.5 inches

So the actual length =

Ans : a. or 12 feet

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.
