Answer 2

Answer:

assum length of this rectangle x

breadth y

Step-by-step explanation:

$x = 5y - 4$

$x + 5y = - 4$

$2x + 2y = 40$

$x + y = 20$

$x = 20 - y$

$x + 5y = - 4$

$20 - y + 5y = - 4$

$4y = - 24$

$y = 6$

$length \: is \: not \: negitive$

$x + y = 20$

$x + 6 = 20$

$x = 14$

area of rectangle=xy

=6×14

=84

it's your answer
