The scale factor of a room for a scale drawing is 2.3. The actual length of a wall in the room is 46 feet and the actual width of the room is 69 feet. What is the area of the scale drawing?
Accepted Solution
A:
There's two ways to solve this. First way: Let's divide the width and length by 2.3. 46÷2.3=20 69÷2.3=30 20×30 600 ft² Second Way: Let's find the area of the actual room. 46×69 3,174 ft² Let's find the scale drawing squared. 2.3²=5.29 3,174÷5.29 600 ft²
