    Do you know what perimeter means? :)

    It's the area surrounding the rectangle(or whatever shape you happen to be working with besides circle) right?

    correct :) So what do you have trouble with for this question? Converting cm to m ? Your rectangular frame looks like this: |dw:1440593503618:dw|

    I just need to know what I'm supposed to do. The formula for a rectangle I believe is length times width. In which case all I would need to do is multiply the two. My problem is the converting part. I'm not sure if I should do something extra.

    that formula you're talking about if for the AREA of a rectangle :) Perimeter of a rectangle = sum of all the sides So, perimeter of the rectangle = 2 times length + 2 times width Perimeter of rectangle = 2( 60) + 2 (50) cm = ? cm

    here is what i mean: Perimeter = SUM (total) of all the sides. |dw:1440593895789:dw|

    So firstly, what does the perimeter/distance equal to in cm?

    yes so perimeter = 220 cm. Now we want to convert 220 cm to meters. So... How many centimeters are in 1 meter ?

    1m = 100 cm Therefore, if we divided both sides by 100 we would get: 0.01 m = 1cm right? Which is the same as 1 cm = 0.01 m So what would 220 cm = ?m we multiplied 1 cm by 220 to get 220 cm So multiply 0.01m by 220 to convert 220cm to meters :)
