The sides of the square is 6 cm with a scale factor of 1.6
So the actual size will be
= 6 * 1.6
= 9.6 cm
Getting the area:
Area = s^2

Step-by-step explanation:
Formlua

As given
In a school, 42% of the students liked to play football and 24% liked to play tennis.
As the percentage is always 100% .
Percentage of students choose swimming = ( 100 - 42 - 24) %
= (100 - 66) %
= 34 %
The rest of the students choose swimming If 170 students choose swimming .
Part value = 170
Percentage = 34 %
Putting all the values in the formula


Total value = 500
As the percentage for students liked to play football = 42%
Putting in the formula



Part value = 210
Thus
Students liked to play football = 210
Therefore the students liked to play football are 210 .
