Question 15(Multiple Choice Worth 1 points) (06.04 MC) The expression to find the perimeter of a rectangle is 2(length + width).

vodomira [7]

Answer: 1 2/3

Step-by-step explanation:

The expression to find the perimeter of a rectangle is 2(length + width)

Length = 1/3

Width = 1/2

Perimeter = 2( 1/3 + 1/2)

Lowest common factor = 6

Perimeter = 2 [ (2 + 3) / 6]

Perimeter = 2 [ 5/6]

Perimeter = 10/6

Perimeter = 1 4/6 = 1 2/3
