Width = 9cm

Length = 18cm

Explanation:

Let width = b,

So, length = 2b

Perimeter of rectangle = 2x(length + width)

According to the question,

$54cm = 2X(2b + b)\\54cm = 2X(3b)\\27cm = 3b\\b = 9cm$

Hence,

Width = 9cm

Length = 18cm

150

Step-by-step explanation:

Given that;

Company A offers;

Salary= $ 17000

commission= $100 per tv set

Company B offers;

To solve this problem, the amount obtained after selling for A option should be equal to B option

Form equations

$17000 +100 x = 29000 + 20x\\\\\\100x-20x= 29000-17000\\\\\\80x=12000\\\\\\x=12000/80 = 150$

The number of televisions sold for the options to be equal = 150
