He lays the long edge of the paper along the long edge of the frame several times and finds the frame is 4 papers long. how long is this in inches?

44 inches

Step-by-step explanation:

A regular sized printer paper is 8.5 x 11 inches. Since the long side is 11 inches,  and there are 4 papers 11 x 4 us 44.

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.
