Answer:
A = 100 [tex]un^{2}[/tex]
Step-by-step explanation:
You have to use the area of a trapezoid formula:
A = [tex]\frac{h}{2}[/tex](a + b)
Now, substitute the values of the height and the bases:
A = [tex]\frac{8}{2}[/tex](10 + 15)
Finally, simplify the equation to solve for the area:
A = 4(25)
A = 100 [tex]un^{2}[/tex]
