a.
21.66 square feet
b.
468.98 square feet
c.
1472.61 square feet
d.
14,519.36 square feet
, i suck at math -w-

Option C is the answer.

Step-by-step explanation:

We have been given that the pond is circular and the measurement of fencing is 136 feet.

In other words we can say that the circumference is 136 feet.

The formula for circumference is = where r is the radius of the circle.

So, we get;

=>

r = 21.65 feet

Area of the circle is given as =

So, the largest area will be =

= 1471.79 square feet. (close to 1472.61 or option C)

i found two solutions,   n = 2 • ± √3 = ± 3.4641

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
