Answer:

<h2>The lenght is 17 miles</h2><h2>The wide is 13 miles</h2>

Let / l : the lenght of the rectangle

w : the wide of the rectangle

Step-by-step explanation:

a = l \times w \\ 221 = (w + 4) \times w \\ 221= w^{2}  + 4w \\  {w}^{2}  + 4w - 221 = 0 \\ (w + 17)(w - 13) = 0 \\ either \: w  + 17 = 0 \\ so \: w =  - 17 \: mile \:  \:  \:  \: neglect \\ or \: w - 13 = 0 \\ so \: w = 13 \\ l = w + 4 \\ l = 13 + 4 = 17 \: mile

I hope that is useful for you

Find the value of x in the triangle shown below
beks73 [17]

Answer:

x = 12

Step-by-step explanation:

Using the Pythagorean theorem where c = 13, and b = 5, we get (a = x):

a^2 + 5^2 = 13^2

Solving for a:

a^2 = 13^2-5^2

a =\sqrt{13^2-5^2}   = \sqrt{144}=12
