Question

Write a polynomial expression that represents the area of the trapezoid. (A=1/2h(b1+b2))

Answer 1

Answer:

$A = 5 {x}^{2} + 6x + 1$

Step-by-step explanation:

$A = \frac{(a + b)h}{2} = \frac{(6x - 5 + 4x + 7)(x + 1)}{2} = \frac{(10x + 2)(x + 1)}{2} = \frac{2(5x + 1)(x + 1)}{2} = 5 {x}^{2} + 6x + 1$
