Question

16. The area of a rectangle is represented by x^2 + 12x+ 20. What is the missing side length of the rectangle?

Answer 1

Answer:

x = 1.43

Step-by-step explanation:

14x = 20

x = 20/14

x = 14.3

Answer 2

Answer:

Length = x + 2

Width = x +10

Step-by-step explanation:

$Area = Length \times Width$

$x^2 + 12x +20 = Length \times width\\\\x^2 + 2x + 10x + 20 = Length \times width\\\\x(x+2)+10(x+2) = Length \times width\\\\(x+2)(x+10) =Length \times width$

Length = x + 2

Width = x +10
