How does the ratio of corresponding side lengths of the two quadrilaterals compare with the ratio of the areas of the quadrilate

Wittaler [7]

Answer:

The ratio of the areas would be the ratio of the side lengths squared.

Say the ratio of the side lengths is 1:2, the ratio of the areas would be 1:4. If the ratio of the sides were 2:3, the ratio of the areas would be 4:9.

Hope this helps

Ulleksa [173]

Answer:

$\huge\boxed{A=24\sqrt2}$

Step-by-step explanation:

<em>Look at the pictures.</em>

<em />

In the ΔAED the sides are in the proportion $1:1:\sqrt2$

Therefore we have the equation:

$|AE|\sqrt2=6\qquad\text{multiply both sides by}\ \sqrt2\\\\2|AE|=6\sqrt2\qquad\text{divide both sides by 2}\\\\|AE|=3\sqrt2$

Therefore

$|ED|=3\sqrt2$

The formula of an area of a parallelogram:

$A=bh\\\\b-base\\h-height$

We have

$base=|AB|=8\\height=|ED|=3\sqrt2$

Substitute:

$A=(8)(3\sqrt2)=24\sqrt2$
