The width of a rectangle measures (5v-4w)(5v−4w) centimeters, and its length measures (3v+7w)(3v+7w) centimeters. Which expression represents the perimeter, in centimeters, of the rectangle?

P = 2( 8v +3w)

P = 16v +6w

Step-by-step explanation:

P = 2 ( l+w) for a rectangle

P = 2((3v+7w)+ (5v-4w))

Combine like terms

P = 2( 8v +3w)

Distribute

P = 16v +6w

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
