A rectangle has a side legnth of 32 cm and a legnth of 55 mm. What is the perimeter of the rectangle in centimeters

First, you must convert 55 mm to cm

55/10 = 5.5 cm

since every cm equals 10 mm

now add up all sides

perimeter = (Length x 2) + (width x 2)

(32 x 2) + (5.5 x 2)

64 + 11

Answer is 75 cm
