Find the perimeter of the polygon with the vertices A (−1, 1), B (4, 1), C (4,−2), and D(−1,−2). The perimeter of ABCD is ___ units.

Could someone explain how I can figure this out?

The perimeter of polygon ABCD is 16 units

The coordinates are given as:

Start by calculating the distance between the coordinates using the following distance formula

So, we have:

The perimeter is then calculated as:

Substitute values for AB, BC, CD and DA

Hence, the perimeter of the polygon is 16 units

Given:

The vertices of a polygon are A (−1, 1), B (4, 1), C (4,−2), and D(−1,−2).

To find:

The perimeter of ABCD.

Solution:

Distance formula:

Using distance formula, we get

Similarly,

Now, perimeter of ABCD is

Therefore, the perimeter of ABCD is 16 units.

there has been genes found in the x chromosome of males that have been linked to [homo/hetero]sexuality. in addition to the reign of the x chromosome, a section of chromosome 8 has also been link to, "alot of ppl are so " these facts were proven true after a 2014 study of a gay male and his strait brother. according to newscientist.com,"chromosome 14 and is mainly active in the thyroid, but also the brain. called tshr, it makes a type of receptor protein that recognises and binds to a hormone that stimulates the thyroid. in this way, the gene plays an important role in controlling thyroid function. the fact that tshr seems to be involved in sexual orientation fits with evidence that thyroid function seems to be linked to sexuality."

in conclusion, "ppl are so gay" due to their genetics.
