Answer:

B)
A=4x+8

Explanation:

Hi there!

Area of a trapezoid:
A=\displaystyle(1)/(2)h(b_1+b_2)

⇒ b₁ = x-3

⇒ b₂ = x+7

⇒ h = 4

Plug the given information into the equation:


A=\displaystyle(1)/(2)(4)[(x-3)+(x+7)]\\\\A=\displaystyle(1)/(2)(4)(x-3+x+7)\\\\A=2(2x+4)\\\\A=4x+8

Therefore, the area of the trapezoid is
4x+8.

I hope this helps!
