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

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.

236 cm 16 time 12 = 192

6 times 7 = 42

192+42
