Answer:

13

Step-by-step explanation:

The perimeter is calculated by multiplying the sum of width and height with 2

2*(4x-2+7x+9) = 300 solve inside the parenthesis

2*(11x+7) = 300 multiply inside the parenthesis with 2

22x + 14 = 300 subtract 14 from both sides

22x = 286 divide both sides by 22

x = 13
