Find the area of the parallelogram that has adjacent sides v =2i + j+ 4k and w = 3i + j-4k. The area of the parallelogram is

A plot of land is in the shape of a rectangle with vertex points of W(8, 9), X(-6, 9), Y(-6, -5), and Z(8, -5). On the northwest corner of the property lies a square house, whose area is 9 umits". The scale factor for the blueprint is 1 unit = 4 feet. Use this information to complete each step below. a. Draw a blueprint to represent this property using the Cartesian Coordinate Plane provided to the right. b. Suppose the property (excluding the house) needs to be covered with grass seed so that their children can play. How many square feet of grass seed will be needed to cover the lawn? c. The owners buy a dog and need to fence in the backyard (exclude the fencing of the north and west faces of the house). How many feet of fencing do they need to purchase? d. If the grass seed costs $0.45 per square foot and the fencing costs $26.30 per foot, how much money will this project cost all together?
