Original area = 12 = \frac{1}{2} * b *h

New Area = \frac{1}{2}* 3b *3h = 9 * (\frac{1}{2} *b *h) = 9 * 12 = 108 ft^{2}

-Dominant- [34]

Answer:

Hi,

Geologists obtain indirect evidence about the earth’s interior by studying seismic waves produced.

Explanation:

Geologists are able to study the layers of the interior of the earth by observing the seismic waves patterns. The recorded data for the waves can show how the waves traveled through the earth and the path followed which will reveal the structure of the interior of the earth. The speed and magnitude of the wave can further reveal the characteristics of the earth’s interior.

Best wishes!
