Help me solve #15 please!!

Formulas if you need them:
RHOMBUS: A = 1/2 (d1)(d2)

Area of the given rhombus = 498.83 ft²

Solution:

Given figure is a rhombus ABCD.

BE = 12 ft and ∠BAE = 30°

Property of rhombus:

Diagonals bisect each other at right angles.

In ΔAEB, ∠BAE = 30°, ∠AEB = 90° and BE = 12 ft

Do cross multiplication, we get

AB = 24 ft

Using Pythagoras theorem,

Taking square root on both sides, we get

ft

AC =

Area of the rhombus =

                                   = 498.83 ft²

Area of the given rhombus = 498.83 ft²

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.
