Alenkinab [10]

Answer:

Area of trapezoid is $16ft^2$ .

Therefore, option 2nd is correct.

Step-by-step explanation:

We have been given both the sides a=3 and b=5.

And height that is h=4

We will use the formula find the area of trapezoid is:

$\frac{a+b}{2}\cdot h$

Substitute the formula we get:

$\frac{3+5}{2}\cdot 4$

$\Rightarrow \frac{8}{2}\cdot 4$

$\Rightarrow 16$ .

Area of trapezoid is $16ft^2$ .

Therefore, option 2nd is correct.
