Well, honey, the perimeter of a rectangle is calculated by adding up all the sides, so for your 23cm long and 10cm wide rectangle, you just add up all the sides: 23 + 23 + 10 + 10 = 66cm. Voilà, you've got yourself a perimeter!

5x2= 10 8x2=16 10+16=26 perimeter= 26!

I would assume it to be 42 ft depending if you are talking about the inside of the room or the outside perimeter

What is a rectangle were the area is 10 and the perimeter

The perimeter of this square measures 4 x 1 = 4 decimeters. As 1 decimeter = 10 centimeters then 4 decimeters = 4 x 10 = 40 centimeters.

That is not a square, it is a rectangle and it has a perimeter of 36 inches.

Perimeter = 2+2+3+3 = 10 feet

28 cm

Perimeter = 2+3+2+3 10 feet
