$\huge\colorbox{white}{Solution࿐ }$

Giiven that,

→ x + y = 36 -------- Eqn.(1)

→ y = (5/7)x ------- Eqn.(2)

→ x - y = 6 -------- Eqn.(3)

Adding Eqn.(1) and Eqn.(3)

→ x + y + x - y = 36 + 6

→ 2x = 42

→ x = 21 .

putting value of x in Eqn.(1)

→ 21 + y = 36

→ y = 36 - 21

→ y = 15 .

checking now,

→ 2 * length - breadth = 27

→ 2 * 21 - 15 = 27

→ 42 - 15 = 27

→ 27 = 27 .
