Answer:

13 units

Step-by-step explanation:

Hello!

The area of a trapezoid is [tex]\frac{b_1 + b_2}{2} * h[/tex].

So, given the area is 100 units², and the height is 10 and one base is 7, solve for the other base:

  • [tex]\frac{b_1 + 7}{2} * 10 = 100[/tex]
  • [tex]\frac{b_1 + 7}{2} = 10[/tex]
  • [tex]b_1 + 7 = 20[/tex]
  • [tex]b_1 = 13[/tex]

The missing base is 13 units.
