Diện tích vườn hao hình vuông là
15 x 15 = 225 ( m2 )
=> Diện tích thửa ruộng = diện tích vườn hao = 225 m2
Chiều rộng thửa ruộng là
225 : 30 = 7,5 ( m )
Chu vi thửa ruộng đó là
( 7,5 + 30 ) x 2 = 75 ( m )
Mong lời giải của mình giúp ích cho bạn ^^

-26 - ( x - 7 ) = 0
=> - x + 7 = 26
=> -x = 26 - 7
=> -x = 19
=> x = -19 nha bạn ^^
