Question

Spencer measured a house and its lot and made a scale drawing. He used the scale 3 inches : 2 feet. In the drawing, the deck is 90 inches long. What is the length of the actual deck?​

Answer 1

answer: the deck is 60ft (720 inches)

if you simplify the scale, it is 1in : 8in

then multiply 90 by 8 to get 720 inches

then covert back to feet
