The statement that correctly describes a property of white light is that it b) contains different wavelengths of visible light.

C. Rectangle.
Just think of it as if you sliced a loaf of bread in half.
Use the Pythagorean theorem:
70^2 = 42^2 + width^2
4900 = 1764 + width ^2
Subtract 1764 from both sides
3136 = width^2
Take the square root of both sides
Width = 56 inches
