Question

Please Help!!

An architectural drawing lists the scale as 1/4” = 1”. If a bedroom measures 3 1/2” by 5 1/2” on the drawing, how large is the bedroom.

Answer 1

B is correct option

Explanation:

The correct option is B:

Convert 3 1/2 inches in feet by proportion:

3 1/2 = 7/2

1/4 / 7/2 = 1/x

1/2 / 7 =1/x

1/2 *x = 7

x= 7*2

x= 14ft

Convert 5 1/2 into feet

5 1/4 = 21/4

1/4 / 21/4 = 1/y

THE DENOMINATORS WILL BE CANCELLED OUT BY EACH OTHER.

1/21 = 1/y

y = 21ft

Therefore it is 14ft by 21ft, which is option B....
