Question

a rectangle has a length of 30 cm and height 53 mm. What is the perimeter of this rectangle in centimeters

Answer 1

70.6 cm

Explanation:

The length is 30 cm so you multiply by 2 which is 60 and the height is 53 mm so you multiply that by 2 and get 106 mm

to convert millimeters to centimeters you just divide the length value by 10 :)

so 10.6+60=70.6 cm
