Answer: 144
Step-by-step explanation: Its probally wrong
We know that
<span>The formula for the area of a quadrilateral with perpendicular diagonals is
</span>A=(0.5)*(D1*D2)
A=58 in²
D1=AC=14.5 in
D2=BD=?
so
D2=2*A/D1-----------> 2*58/14.5-----------> D2=8 in
BD=D2=8 in
the answer is
BD=8 in
A-k = w + v
a-k = w + v
+k +k
the k’s on the left side cancel out
a = w + v + k
