Answer 2

we know that

The area of a Kite is equal to

$A=\frac{1}{2}(D1*D2)$

where

D1 and D2 are the diagonals of the kite

In this problem we have

$A=51.68\ in^{2}$

$D1=15.2\ in$

Substitute in the formula and solve for D2

$51.68=\frac{1}{2}(15.2*D2)$

$103.36=(15.2*D2)$

$D2=103.36/15.2$

$D2=6.8\ in$

therefore

the answer is the option B

$6.8\ in$
