The length of a rectangle is 2 units shorter than one-fifth of the width, x.
which expression represents the perimeter of the rectangle?
a. 2/5x−4
b. 12/5x−2
c. 12/5x−4
c. 2/5x−8

C.

Step-by-step explanation:

Width = x

Length = one fifth of width minus 2

Length =

Perimeter is given by the formula

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.
