Which equation would best solve the following problem?
maria releases a javelin 1.5 meters above the ground with an initial vertical velocity of 22 meters per second. how long will it take the javelin to hit the ground?
–4.9t^2 + 22t + 1.5 = 0
–4.9t^2 + 22t = 1.5
–4.9t^2 + 1.5t + 22 = 0
–16t^2+ 22t + 1.5 = 0

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?
