Can anyone help me, please?

30cm

Step-by-step explanation:

First I added 6 and 13 to get 19 then i said that they were going straight down to measure the sides so that means you need to multiply 5 times 2 and get 10 but the sides are tilted so if the sides are tilted then you need to add a half more for each because they are actually a little bit bigger then what they are saying so now you have 5 1/2 plus 5 1/2 and that gets you to 11 and 11 plus 19 is 30

hope this helps!

Please mark me as brainliest

step-by-step explanation:

you have to realize that a line equals 180 degrees

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
