2x² + 5x -6x - 15 = 0

Find the area of the trapezoid.

anzhelika [568]

Answer:

488 sq ft

Step-by-step explanation:

Alright, so:

The formula for the area of a trapezoid is as follows:

$A=\frac{a+b}{2} h$

In this case, a and b are the bases.

Insert the values into our equation and we have...

$A = \frac{39+17}{2} (16)\\A = \frac{56}{2} (16)\\A = 488ft^{2}$
