Wouldnt you add all of those up and subtract from 38?

Okay since it is a quadrilateral it has 4 sides. Since you are given 3 sides and the perimeter you must find x. 38=5.8+7+11.2
sorry I have to go
but yes you do that

Thank you!

anonymous · Answer

do 38 minus the the sum of the 3 sides. that should give you the unknown length

38-(5.8+11.2+7)=
38-24=
