Answer:
16 feet in length.
Step-by-step explanation:
In this situation, you are given the area and the width of the full carpet, furthermore, you must reverse the formula for area to find the length, as so:
<u>Area Formula</u>: A=<em> l • w</em>
<u>Given</u>: 136= <em>l</em> • 8.5
<em>l</em> = 136 ÷ 8.5
<em>l</em> = 16 feet

Answer: OPTION D.
Step-by-step explanation:
You have the expressions given in the problem:

To find the product of both expression you must multiplicate them.
You must multiply the numerators of both expression and the denominators of both expression.
Keeping the above on mind, you obtain that the product is:


The x coordinate of S will be 1/2 * 2a = a.
and since the half triangle is 30-60-90 the y coordinate will be sqrt3 a
so S is (a , sqrt3a)
Here it is! Have a nice day. :)
(a.) is the answr. ............................................
