I can honestly swear this is the hardest I done if someone could explain that would be great.

Thsi question has already been answered similarly:

You could use the same formula that was shown, just with your numbers instead.

Hope this helps ;P

Right because they are different nuumebers. Just substitute the numbers here with that formula.

Yes, I see that all those empty answers you gave and half posted questions were proably one special addition the forum XD ; )

But then you asked the same question, and you got a different response:

If you were to substitute your answers with the ones in the formula, it would look like:

\((1/2) (9.5)(12+7)\)

\((1/2)(9.5)(19) = 90.25 \)

So it would be 90.25 square inches

Another method used was the 1/2*b*h:

\(1/2*7*9.5= 33.25\)

\(1/2*12*9.5 = 57\)

Then add the two:

\(57+33.25= 90.25\)

You get the same answer of 90.25 square inches

The expression (1/2)*b*h refers to a *single* triangle.

The kite can be considered as *two* large triangles of base 19in and height 9.5in; or *four* triangles, two of base 12in and height 9.5in, and two of base 7in and height 9.5in.

Hence you should double your result of 90.25 in^{2}.

The area for a right angle triangle is B*H divided by two. But since there's two of the same triangle, if they were put together they'd make a rectangle.

The only method that I found that has the answer as one of the choices is:

\(7*9.5=66.5\)

\(12*9.5=114\)

\(114+66.5=180.5\)

180.5 Square inches

Hope this helps ;P
