The height of the flagpole is three fourths the height of the school. The difference in their heights is 4.5 m. What's the height of the school? Choices for school's height: 18, 20, 24. Please show work

h = the height of the flagpole
s = the height of the school
h = ( 3 / 4 ) s
s  h = 4.5 m
s  ( 3 / 4 ) s = 4.5
( 1 / 4 ) s = 4.5 Multiply both sides by 4
s = 18
The height of the school = 18 m
