Find the area of ABCD

scoray [572]

Answer:

<u>Applying Heron's Formula</u>

$s=\frac{2.89+4.3+6.81}{2}$

$s_1=7$

$A_1=\sqrt{7(7-2.89)(7-4.3)(7-6.81)}$

$A_1=10.56$

Now, $s_2=\frac{6.81+8.59+7.58}{2}$

$s_2=11.49$

$A_2=\sqrt{11.49(11.49-6.81)(11.49-8.59)(11.49-7.59)}$

$A_2=24.69$

<u>Total Area: </u>

<u /> $10.56+24.69$

$=35.25$

Given: WZ is perpendicular to VY, WZ bisects VY, VZ = 2x+2, and ZY = 3x-4

zhenek [66]

The measure of VY is 28 units

<u>Solution:</u>

To find: The measure of VY

From the given,

WZ bisects VY, then we can conclude that VZ = ZY ---> (1)

VZ=2x+2 and ZY=3x-4

Substituting the above values in (1) we get,

$2x+2=3x-4\rightarrow2x-3x=-4-2$

$\Rightarrow-1x=-6\rightarrow-x=-6$

$\Rightarrow x=6$

Since, WZ bisects VY, VY=VZ+ZY ---> (2)

On substituting the value of x in (2) we get,

$VY=(2x+2)+(3x-4)=(2\times6+2)+(3\times6-4)$

$VY=(12+2)+(18-4)\rightarrow VY=(14)+(14)$

$\Rightarrow VY=28 \text{ units }$
