we're gonna find the dimensions of the rep Tango one. You know that the ratio of the linked to the witness by 24 and the perimeter is 72. This this problem number 20. So we know that length over with it's gonna equal to five over four and the perimeter equals 72 inches. So that means that the perimeter is gonna be too times five X plus two times or ex equal 72. So what we're gonna do is we're gonna find out what the exits here, 10 X plus eight x it's gonna be 72. 18 axe equal 72 devivo 18. Our ex is gonna be four. So now we can take that and we can substitute that back yet. So if we know that the length it's five acts we're gonna take and substitute foreign soar like it's gonna be 20 inches are with we said was for X so we can take them. Excuse me the four times before, we're gonna get 16 inches. So that is our dimensions
