Answer:
7.5 sq. un
Step-by-step explanation:
Hello!
The height is 3 units, the base is 4 units, and the other base is 1 unit.
Using the trapezoid area formula, [tex]A = \frac12(b_1+b_2)h[/tex], we can plug the values in and solve.
Solve:
- [tex]A = \frac12(b_1+b_2)h[/tex]
- [tex]A = \frac12(1 + 4)3[/tex]
- [tex]A = \frac12(5)(3)[/tex]
- [tex]A = 2.5(3)[/tex]
- [tex]A = 7.5[/tex]
The area is 7.5 sq. un
