Step-by-step explanation:
Perimeter = 2(length) + 2(width)
let x represent the width
[tex]304 = 2x + 2(x + 40)[/tex]
[tex]304 = 4x + 80[/tex]
[tex]224 = 4x[/tex]
[tex]x = 56[/tex]
this means that the width is 56cm
sub this into the length:
length = 56 + 40
= 96cm
Answer:
96,56
Step-by-step explanation:
Perimeter = 2(length) + 2(width)
width=x
304=2x+2(x+40)
304=4x+80
224=4x
x=56
lenght=56+40
=96
width=56 cm
lenght=96cm
