12 feet wide and 20 feet from one corner to the opposite corner how long is the storage unit?

12x2 20x2 =40+24=64

Step-by-step explanation:

16 feet long.

Step-by-step explanation:

By the Pythagoras theorem:

20 = L^2 + 12^2     where the length = L.

L^2 = 20^2 - 12^2

= 400 - 144

= 256

L = sqrt 256

= 16 feet.

right

step-by-step explanation:

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
