Question

An architectural drawing has a scale of 2 in=5 feet. If living room is 15 feet by 18 feet ,what is the living room size . What is the area of the living room in drawing. What is the area of actual. Living room . How do they compare. Using proportion and scale drawing

Answer 1

15 ft * 2 in/ft = 30 in
18 ft * 2 in/ft = 36 in

so area on plan = 30*36 = 1080 in^2

on the real size area = 15*18 = 270 ft^2

well to compare them change in^2 to ft^2
there are 12 in /ft
so 144 in^2 per ft^2
so
1080 in^2 *1 ft^2/144 in^2 = 7.5 ft^2

or you could say
30 in = 30/12 ft
36 in = 3 ft
area = 90/12 ft^2 = 7.5 ft^2 luckily :)
