Answer:

Length is 30cm

Width is 13cm

Step-by-step explanation:

Let the width be x cm;

The length will be 2x + 4 cm

Perimeter = 86cm

Perimeter is given by (2 × length) + (2 × width)

2(2x + 4) + 2x = 86cm

4x + 8 + 2x = 86cm

6x = 86 - 8 = 78cm

x = 78/6 = 13cm

Width (x) = 13cm

Length = 2(13) + 4 = 26 + 4 = 30cm
