Answer:
lenght=16 and breath=11
Step-by-step explanation:
let the breath be 'x' if breath equals 'x' then lenght will be 2x-6 as the perimeter is 54 tgen the formula of finding 'x' will be.
=》2(x + 2x - 6) = 54
=》2x + 4x - 12 = 54
=》6x - 12 = 54
=》6x = 54 + 12
=》6x = 66
=》x = 66/6
=》x = 11
so breath =11
and lenght =11×2-6=16
