Alex is planning to surround his pool abcd with a single line of tiles. how many units of tile will he need to surround his pool? round your answer to the nearest hundredth.

a coordinate plane with quadrilateral abcd at a 0,3, b 2,4, c 4,0, and d 2,-1. angles a and c are right angles, the length of segment ab is 2 and 24 hundredths units, and the length of diagonal bd is 5 units.

8.96
10.48
13.42
20.42

the answer is c

Step-by-step explanation:

Third option.

Step-by-step explanation:

The perimeter of a rectangle can be calculated with this formula:

Where "l" is the lenght and "w" is the width.

We can idenfity in the figure that the width of the pool is:

In order to find the lenght, we can use the Pythagorean Theorem:

Where "a" is the hypotenuse and "b" and "c" are the legs of the right triangle.

In this case, we must solve for one of the legs:

Where:

Substituting values, we get:

Then, the perimeter of the pool is:

Alex will need 13.42 units of tile to surround his pool.

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
