Answer 1

3a + 2b

Explanation:

The perimeter of the rectangle is calculated by following formula:

2×(w+l)

• w: width, l: length

Let x represent the missing side length, width,

2(x + 5a - b) = 16a + 2b

• Multiply inside the parenthesis 2

2x + 10a - 2b = 16a + 2b

• transfer 10a - 2b to the other side of the equation

2x = 16a + 2b - 10a + 2b

• Add/subtract like terms

2x = 6a + 4b

• Divide both sides by 2

x = 3a + 2b
