Question

Need help on this pls

Answer 1

Alright, lets get started.

As per the scale, $\frac{1}{4} '' = 1 '$

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

As per the drawing, the dimention of bedroom is $3\frac{1}{2} ''$ and $5\frac{1}{4} ''$.

Means

$3\frac{1}{2} '' = 3 + \frac{1}{2} = 3 + 0.5 = 3.5''$

converting into feet, we need to divide with 0.25.

Means the first dimension would be : $\frac{3.5}{0.25} = 14 '$

Converting $5\frac{1}{4}$ into decimal : 5 + 0.25 = 5.25

Similarly, the second dimension in feet would be : $\frac{5.25}{0.25} = 21 '$

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

Hope it will help :)
