Find the area of a kite ABCD if BD= 48cm, AB= 25cm, and BC= 26cm?
1 Answer
Explanation:
The formula of a kite's area is
where
In the problem, be noticed that once the diagonal BD has an endpoint in B (where 2 segments of different sizes, AB and BD, meet), this diagonal is divided in two equal parts by the other diagonal. Calling E the point where the two diagonals intercept each other, we have:
In the right triangle ABE we can obtain the segment AE
In the right triangle BCE we can obtain the segment CE
In this way we discovered the previously unknown diagonal:
Finally,
