Answer:
7.17 cm
Step-by-step explanation:
If the width is x, the length is twice this = 2x
And
Perimeter = 2 (W + L)
so
Perimeter = 2 ( x + 2x)
Perimeter = 2 (3x)
Perimeter = 6x
43 = 2 ( x + 2x )
43= 2 ( 3x)
43 = 6x
= 7.17 cm
Hope this helps i'm pretty sure this is how you do it :-)
90 + (5x-1) + 8x = 180
90 + 5x - 1 + 8x = 180
89 + 5x + 8x = 180
89 + 13x = 180
13x = 91
x = 7
