An architect is looking at a 1:12 scale model of a building which is in the shape of a rectangular prism. The building will be reinforced with steel support beams along the perimeter of each lateral face of the structure. If the scale model has about 42 feet of support beams, how many feet of steel support will be needed to build the actual building?

A ladder 42 feet long is placed so that it will reach a window 30 feet high (first building) on one side of a street; if it is turned over, its foot being held in position, it will reach a window 205 feet high (second building) on the other side of the street. How wide is the street from one building to the other?

A contractor plans to build an artist's studio with a roof that slopes differently on the two sides (Figure $6-7 \mathrm{a}$ ). On one side, the roof makes an angle of $33^{\circ}$ with the horizontal. On the other side, which has a window, the roof makes an angle of $65^{\circ}$ with the horizontal. The walls of the studio are planned to be 22 ft apart. (FIGURE CANNOT COPY) a. Calculate the lengths of the two parts of the roof. b. How many square feet of paint will be needed for each triangular end of the roof?
