HEYA!!
---------
Let the Length of the Park be X m
Then Breadth of the park = ( X - 7 ) M
Perimeter of Rectangle = 2 × ( L + B )
Perimeter Given = 1034 m
So we have ,
2 × ( X + X - 7 ) = 1034
2 × ( 2X - 7 ) = 1034
(2X - 7 ) = 5 17
2X = 517 + 7
2X = 524
X = 262
〰Length of plot is 262 m
〰Breadth of plot is 255 m

Let length be = x m
let breadth be = (x-7)m
Perimeter of a rectangle = 2(l + b)
1034=2 (x+(x-7))
1034= 2(x+x-7)
1034= 2(2x-7)
1034= 4x-28
1034+28=4x
1062=4x
1062/4=x
265.5m=x(length)
258.5m=x-7(breadth)
