Question

)A scale drawing of a living room is shown below:

attached file below.

What is the area of the actual living room in square feet? Round your answer to the nearest whole number.

17 ft2
41 ft2
495 ft2
103 ft2

Answer 1

the scale is 1 to 30

each inch on the drawing goes to 30 inches in real life

Answer 2

so change over the lengths to the real world values, by multiplying them by 30 , then you can get the area

Answer 3

okay, so I multiply?

Answer 4

Just noticed, you need to change them to feet, they want square feet...

Answer 5

yeah the scale 1 to 30, 5.5 inch goes to 5.5*30 inch , same for other dimension

Answer 6

okay I got 165 and 90

Answer 7

right, so the living room is 165 x 90 inches, i would change those both to ft before multiplying them together for the area

Answer 8

dimensions in feet

165/12 ft x 90/12 ft

Answer 9

The area is Length times width for the room

\[A = \frac{ 165 }{ 12 }*\frac{ 90 }{ 12 } = \frac{ 14850 }{ 144 } ft^2\]

Answer 10

you can reduce the fractions before multiplying them to not have huge numbers, but tha tis the answer
