Question

The Drawing below represents a scale drawing of a room, when 1 inch = 16 feetwhat is the approximate area of the store in square feet

Answer 1

we know that

The scale drawing is

1 in=16 ft

To find out the actual area convert the dimensions of the model to feet

so

Multiply by the scale factor

4 in=4*16=64 ft

3 in=3*16=48 ft

2 1/4 in=2.25 in=2.25*16=36 ft

1 3/4 in=1.75 in=1.75*16=28 ft

Find the area of the room in square feet

so

the area is equal to

(64*28)+(36)*(48-28)=2,512 ft^2

therefore

the approximate area is the option A
