This is urgent plz send me fast I have maths exam of class 7 plz.​

Answer 1

let length of rectangular plot »x.

let the breath of rectangular plot »x-10

let of fence »perimeter

»5x -10-22

»5x-32

According To The Question

$2(x + x - 10) = 5x - 32 \\ perimeter \: \\ 2(2x - 10) = 5x - 32 \\ 4x - 20 = 5x - 32 \\ 32 - 20 = 5x - 4x \\ 12 = x$

so length of plot: x»12

" breath " " : x-10 » 12-10 »2
