Find the area of the trapezoid

fiasKO [112]

Answer:

C. $52\sqrt{3}\ ft^2$

Step-by-step explanation:

Use formula for the area of trapezoid

$A=\dfrac{a+b}{2}\cdot h,$

where a is the smaller base, b is the larger base and h is the height.

From the diagram,

$a=11\ ft\\ \\b=15\ ft\\ \\h=4\sqrt{3}\ ft$

So, the area of trapezoid is

$A=\dfrac{11+15}{2}\cdot 4\sqrt{3}=13\cdot 4\sqrt{3}=52\sqrt{3}\ ft^2$
