The area of a trapezoid is 65 feet squared. The height is 10 feet and the length of one of the bases is 9 1/2 feet. Find the length of the other base.

Area of trapezoid = (base1+base2) times 1/2 times height

aera=65

height=10

one of th ebases is 9 and 1/2

area = (base1+base2) times height times 1/2

65 = (9 and 1/2+base2) times 10 times 1/2

65 = (9 and 1/2+base2) times 5

divide both sides by 5

13=9 and 1/2+base2

subtract 9 and 1/2 from both sides

3 and 1/2

the legnth of the other base=3 and 1/2 feet
