Part 1) <span>Find the area
we know that
the area of the triangle is
A=b*h/2
in this problem
b=9
h=12
so
A=9*12/2-----> A=54 units</span>²
the answer part 1) isArea=54 units²Part 2) <span>Find the area of the kite
see the picture attached with letters to better understand the problem
we know that
The area of a Kite is </span><span>half the product of the diagonals
</span><span>
step 1
find CB
applying Pythagoras Theorem
AB</span>²=AC²+BC²------> BC²=AB²-AC²-----> BC²=5²-3²----> BC²=16
<span>BC=4
so
the diagonals are
(10+4) and (3+3)---------> 14 and 6
Area=(1/2)*[14*6]----> Area=42 units</span>²<span>
the answer Part 2) isthe area of a kite is 42 units</span>
