Answer:
it is the 1st one
Step-by-step explanation:
because you have to add up all three sides because you need 180 then subtract that answer from 180 and you will get your answer
<span>Area of the base = 3*4 / 2 = 6
</span><span>Area of BOTH bases = 12 sq inches
Area of one face = 3 * 7 = 21 sq inches
</span>Area of 2nd face = 4 * 7 = 28 <span>sq inches
</span>Area of 3rd face = 5 * 7 = 35 <span>sq inches
TOTAL Area = 96 </span><span>sq inches</span>

Given:
The number of sides of given polygon = 4
To find the sum of the interior angles of the polygon.
Formula
The sum of interior angles of any polygon is
where, n be the number of sides of the polygon.
Now,
Taking n = 4 we get,
or, 
or, 
Hence,
The sum of the interior angles of the polygon is 360°.
