Answer:
12 sqrt (10)
Step-by-step explanation:
S = (12 + 11 + 7) / 2 = 15
A = sqrt (s(s-a)(s-b)(s-c))
= sqrt (15(15-12)(15-11)(15-7))
= sqrt (15*3*4*8)
= sqrt (1440)
= 12 sqrt (10)

Answer:
900 degrees
Step-by-step explanation:
This question is asking you to figure out what all the angles in the shape add up to. There is actually a formula for this: a function of the number of sides that a polygon has.
> Memorize this formula if you will need to do these kinds of problems for your tests/quizzes!
(n - 2) * 180
Since this polygon has 7 sides, we substitute n = 7 into the formula, and solve.
(7 - 2) * 180
5 * 180 = 900
The sum of the interior angles of the polygon shown is 900 degrees.
