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

Answer:
89.44
Step-by-step explanation:

This answer is closest to 89.44
