Accepted Solution

A:

we know that

the scale is is 1/2 inch = 4 feet

using a graph tool

the approximate measurements in the drawing are

5 cm x 4 cm

convert to in

5/2.54--------> 1.97 in

4/2.54------> 1.57 in

convert drawing to actual

if 0.5 in---------> 4 ft

1.97in-------> X

X=1.97*4/0.5------> X=15.76 ft

if 0.5 in---------> 4 ft

1.57 in-------> X

X=1.57*4/0.5------> X=12.56 ft

the approximate area of Quinto's bedroom is 12.56*15.76=197.95 ft²

the answer is

the option C)192 ft²
