Answer:
322.24 meters
Step-by-step explanation:
The scale is 4 meter per centimeter. Multiply 5.3 by 4 to get 21.2 meters. Multiply 5.3 by 4 to get 15.2 meters. Multiply 21.2 by 15.2 to get 322.24
8.16 because .016 is not as close to a whole as .16
Area= l*b
0.8=3.2*x
0.8/3.2=x
x=0.25 units
Sarah got £48, Liam got £32, and Emily got £112
