Therefore, the value of C should be (11/2)^2
<span>To square a fraction, take the square of the numerator and put it over the square of the denominator. So since 11^2=121 and 2^2=4, (11/2)^2
(11)^2/(2)^2=121/4

Now, replace the value of c into the other equation:

Using distributive property

However, keep in mind that this is true for:

about 500
54 is about equal to 50 and 12 is about equal to 10, 50*10 = 500
