Nick's dad wanted to measure the length of his backyard and asked Nick to do this with his footsteps. Since it was winter, they were able to count their footprints in the snow starting from the end of the backyard moving in the same direction towards the front. In some places, Nick and his dad's footprints coincided. Eventually, they counted 67 footprints, including their first step. What is the length of the backyard in meters, if the Nick's footstep is 51 cm long and his dad's is 68 cm long?

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?
