4+6.3=10.3

Step-by-step explanation:

BD=ED=1/2*BD=3

5^2-3^2=4^2; EC=4

7^2-3^2=≈6.3

AC=AE+EC=4+6.3=10.3

last option: rhombus or kite

step-by-step explanation:

a kite and rhombus have the same shape. as we don't have any specific formula for the calculation of area of kite. the diagonals are used to calculate the area of a kite or rhombus.

the formula for area of rhombus is given by:

here, d_1 is the first diagonal and d_2 is the second diagonal.

so,

last option is the correct answer ..

the solution is h=10 because you add 9 to each side of the equation.
