Known :

x = 8 units

y = 2 units

h = 10 units

Asked :

A = ...?

Answer :

[tex]A = \frac{a + b}{2} \times h \\ A = \frac{x + (x + 2y)}{2} \times h \\ A = \frac{8 + (8 + 2(2))}{2} \times 10 \\ A = \frac{8 + (8 + 4)}{2} \times 10 \\ A = \frac{8 + 12}{2} \times 10 \\ A = \frac{20}{2} \times 10 \\ A = 100 \: {units}^{2} [/tex]

So, the area of the trapezoid is 100 units² (C)

Hope it helpful and useful :)
