If the area of a trapezoid is 104 cm squared , a = 4x -1 cm, b = x+2 cm , and h = 8 cm , calculate the length of the longer base

The formula of an area of a trapezoid:

We have:

Substitute:

The longer base is a = 4x - 1.

Substitute the value of x to the equation:

19 cm.

36/60

36/2=18

60/2=30

18/30

18/3=6

30/3=10

6/10

6/2=3

10/2=5

your final answer would be 3/5 of an

hope this !

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!
