Randy dilated △SAL with GeoGebra and found the area of the preimage △SAL to be 28 square units and the area of the image △S′A′L′ to be 90.72 square units. After erasing them, he remembered only the height of the preimage was 8 units. Questions: a) What is the scale factor for the dilation? b) Find the altitude "a" for the image. Please answer both questions above and thank you so much :)
