Question

The bases of an isosceles trapezoid are represented by 3x and (3x + 4). The height of the trapezoid is represented by (x + 2). Which polynomial expression BEST represents the area of the trapezoid?
A) 3x2 + 8x + 4
B) 6x2 + 8x + 4
C) 6x2 + 16x + 8
D) 9x2 + 12x

Answer 1

answer is A.

A. 3×2 + 8× +4

Answer 2

3x² + 8x  + 4 polynomial expression BEST represents the area of the trapezoid

Step-by-step explanation:

Two parallel sides of trapezoid are  3x  & 3x + 4

Height  between parallel sides = x + 2

Area of Trapezoid = (1/2)(3x + 3x + 4) (x + 2)

= (1/2)(6x + 4)(x + 2)

= (3x + 2)(x + 2)

= 3x² + 6x + 2x + 4

= 3x² + 8x  + 4

3x² + 8x  + 4 polynomial expression BEST represents the area of the trapezoid
