An architect plans to make a drawing of the room of a house. The segment LM represents the ceiling of the room. He wants to cons
truct a line passing through Q and perpendicular to side LM to represent a wall of the room. He uses a straightedge and compass to complete some steps of the construction, as shown below:
Divide the 30 from the 4 and you will get 7.5 and then divide the 45 from the 2 and you will get 22.5 and then times 7.5 by 9 and then you will get 67.5 and then do the same with the 22.5 with the 6 and then add them up and you will get 202.5
