Answer 1

$let \: the \: length \: and \: breadth \: of \: the \: plot \: be \: 8x \: and \: 5x \: respectively \\ area \: of \: rect. \: park \: = l \times b \\ = 8x(5x) \\ = 40 {x}^{2} \\ length \: and \: breadth \: of \: larger \: rect. \: are \: 8x + 3 \: nd \: 5x + 3 \\ area \: of \: larger \: rect. = l \times b \\ = (8x + 3)(5x + 3) \\ = 40 {x}^{2} + 24x + 15x + 9 \\ = 40 {x}^{2} + 39x + 9 \\ area \: of \: plot = area \: of \: larger \: rect. - area \: of \: park \\ 594 = 49 {x}^{2} + 39x + 9 - 40 {x}^{2} \\ 594 = 39x + 9 \\ 594 - 9 = 39x \\ 39x = 585 \\ x = \frac{585}{39 } \\ x = 15 \\ dimensions \: \: r \: 8x \: and \: 5x \\ = 8(15) \: nd \: 5(15) \\ = 120 \: nd \: 75 \\ hope \: it \: helps \: u \\ plz \: mark \: it \: brainliest$
