The amount of canvas needed would be the sum of the areas of each face of the pyramid. Each triangular face would have an area of (1/2)bh, where b is the base (6ft) and h is the slant height (7ft). Plugging in these values, we get (1/2)(6ft)(7ft) = 21ft^2 for each triangular face. There are four triangular faces, so the total area of canvas needed is 4(21ft^2) = 84ft^2. Rounded to the nearest whole number, the BEST measurement is therefore 84ft^2.
Answer: D) 76ft^2
