67.33. You would first find the total height of people. So 50 would be multiplied by 68, giving you the answer of 3,400. After, you would subtract 82 and 86, giving you 3,232. To get the final answer you would divide the value by 48, since two of them are removed, giving you 67.33.

A house sits on a rectangular piece of land. Two of the sides measure 104 feet each. If all four sides add to 576 feet, how long

xxTIMURxx [149]

Answer:

Each of the other side is 184 feet.

Step-by-step explanation:

Given that:

Length of two sides each = 104 feet

Total length of all sides = 576 feet

Let,

x be the length of other one side.

Length of other two sides will be 2x.

Total length of sides = 2x + 2(104)

576 = 2x + 208

2x = 576 -208

2x = 368

Dividing both sides by 2

$\frac{2x}{2}=\frac{368}{2}\\x=184$

Hence,

Each of the other side is 184 feet.
