Let's do this question, the perimeter of a trapezius 52 centimeter and e nonpareil side is equal to
10 centimeters.
So it's an isolationist tropism with its height as eight centimeter its area is.
So you need to find the area of the video, give it a try, and then let's do it together.
All right.
Let's do it together.
We know that the area of trapezius is equal to its by two in to some of parallel sites.
Now, let's take a rough diagram over here.
Say this is the isosceles trapezius.
Right.
And let this be let this be these are the two parallel sides and let this be X and let this be X.
Now you can see that A plus B can also be written as a millimeter of the tropism, minus two times X.
Right.
So let's do that, because over here we are given the perimeter and we are given the nonpareil side.
So I can write this as eight by two because it is eight.
Right.
So this is eight by two in the perimeter, minus two times the normal size right over here.
Mm.
Minus two X gives you A plus B, right.
So that would be eight by two in the 52, minus two in the ten and that's four in the 32 which gives
us one twenty eight centimetre square the area.
And that is your answer, which is option C over here.
