Professional pizza ovens are often lined with stone or brick. This is so heat is stored up and redistributed evenly. To get a similar result at home, pizza stones can be used. Pizza stones are made of the same material that lines blast furnaces and kilns so they can withstand ultra-high temperatures.
An 8-inch diameter pizza stone costs $14.35. Marco estimated that a 16-inch diameter pizza stone (same thickness) should cost $28.70. Based on the areas of the two pizza stones, is Marco’s estimate reasonable? Explain your answer.

A wire is bent into the shape of a rectangle with a width of 7 and a length of 12.
The wire is then bent into a different shaped rectangle which is not a square. Sketch such a rectangle below and find the values for its length and width. Show and explain how you found these numbers.
