Question

Need help on this pls

Answer 1

Alright, lets get started.

As per the scale,
`(1)/(4) '' = 1 '`

Means 0.25 '' = 1 ' (symbol '' denotes inches and ' denotes feet)

As per the drawing, the dimention of bedroom is
`3(1)/(2) ''` and
`5(1)/(4) ''`.

Means

`3(1)/(2) '' = 3 + (1)/(2) = 3 + 0.5 = 3.5''`

converting into feet, we need to divide with 0.25.

Means the first dimension would be :
`(3.5)/(0.25) = 14 '`

Converting
`5(1)/(4)` into decimal : 5 + 0.25 = 5.25

Similarly, the second dimension in feet would be :
`(5.25)/(0.25) = 21 '`

Hence the dimension of bedroom will be 14 ft by 21 ft : Option A : Answer

Hope it will help :)
