Write an area word problem so that the solution is 36 square units

Find the area of a cardboard box with a length of 9 inches and a width of 4 inches.

Step-by-step explanation:

9 in × 4 in = 36 in²

your answer would be 12

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
