Actual Area=5,400 (in.)²
Step-by-step explanation:
Scale: 1 cm=7.5 in.
Drawing is 8 cm by 12 cm
Drawing Length=12 cm
Actual Length=Scale factor×Drawing Length=(7.5×12)=90 in.
Drawing Width=8 cm
Actual Width=Scale factor×Drawing Length=(7.5×8)=60 in.
Actual Area=(Actual Length×Actual width)=(90×60)=5,400 squared inches
Actual Area=5,400 (in.)²
