92631
thats the answerrrrrrrrrrrrrrrrrrrr
Let the width be : x
length : (2x - 6)
(2x - 6) (x) = 2x square - 6x
2x square - 6x = 140
2x square - 6x - 140 = 0
if you use the cross method or calculator you’ll get :
( x - 10 ) ( x + 7) = 0
x = 10 or x = -7 ( reject because negative )
so we use x = 10.
width = 10
length = 2(10) - 6 = 14
