(2) The ceiling of Katie’s living room is a square that is 25 ft long on each side. To decorate for a party, she plans to hang crepe paper around the perimeter of the ceiling and then from each corner to the opposite corner. (just 2 diagonals) Katie can buy rolls that each contain 30 ft of crepe paper. What is the minimum number of rolls she should buy?
(assume the crepe paper is hung flush with the wall and ceiling)
Use special right triangles to find the answer. Using any other method will result is 0 points. Show ALL work.

the answer is..
25^2 + 25^2 = c^2 625 + 625 = c^2 c^2 = 1250 c = 35.4
25 + 25 + 25 + 25 + 35.4 + 35.4 = 170.8 (round up to 180) 180 / 30 = 6 rolls
The minimum number of rolls she should buy is 6 rolls

Part a what is the area of triangle i? show your calculation. part b triangles i and ii are congruent (of the same size and shape). what is the total area of triangles i and ii? show your calculation. part c what is the area of rectangle i? show your calculation. part d what is the area of rectangle ii? show your calculation. part e rectangles i and iii have the same size and shape. what is the total area of rectangles i and iii? show your calculation. part f what is the total area of all the rectangles? show your calculation. part g what areas do you need to know to find the surface area of the prism? part h what is the surface area of the prism? show your calculation. part i read this statement: “if you multiply the area of one rectangle in the figure by 3, you’ll get the total area of the rectangles.” is this statement true or false? why? part j read this statement: “if you multiply the area of one triangle in the figure by 2, you’ll get the total area of the triangles.” is this statement true or false? why?
