4.Assume the height of the flagpole is h.
h/5 = 14/3.5
h = 20(feet)
so the height of the flagpole is 20 feet.
5.Because the ratio of the corresponding sides of the two rectangle is 1/(3/4) = 4/3
so the ratio of the areas of two regtangle is 4/3 X 4/3 = 16/9
h/5 = 14/3.5
h = 20(feet)
so the height of the flagpole is 20 feet.
