20+10+10+6+4=50 socks in total, therefore 10/50 =1/5
Assuming it forms a right triangle with the side of the building, you could just use the Pythagorean Theorem to find the height. The ladder would be the hypotenuse, so you would substitute that as c into the equation. The 4 feet could be either a or b; it doesn't really matter. Plug it into (a^2)+(b^2)=(c^2), and you would get. (4^2)+(b^2)=(14^2); simplified, it is (16)+(b^2)=(196). Subtract 16 from 196 to get 180, and you see that (b^2) is equal to 180. Just take the square root of that to get your answer, which would be 6 sqrt5.
To make the pattern it only uses a horizontal translation and a 180 rotation, so the second one.
Hope this helps.
You can split this shape into two shapes; a rectangle on top and a horizontal rectangle underneath. The top rectangle would be 4 x 2 = 8 square units, and the bottom rectangle would be 7 x 1 (3 - 2) = 7 square units. Now you just add these to get 15 square units. I hope this helps!
