Well, the area of a trapezoid is A = (b_{1} + b_{2}) * h * 1/2 so you can use the area of a parallelogram, which is A = l * w, by splitting the trapezoid into 2 triangles and one rectangle. So you'd use A = l * w for the rectangle and A = 1/2bh for the triangles. You'd get the same answer!

Points (2, 0) and (0, 3) lie on line k. What is the slope of the line that is perpendicular to k? A. 3/2 B. - 3/2 C. 2/3 D. unde
Otrada [13]

Slope of a Line Passing through two points (x₁ , y₁) and (x₂ , y₂) is given by :

\heartsuit\;Slope(m) = \frac{y_1 - y_2}{x_1 - x_2}

here x₁ = 2 and x₂ = 0 and y₁ = 0 and y₂ = 3

\heartsuit\;Slope(m) = \frac{0 - 3}{2 - 0} = \frac{-3}{2}

⇒ Slope of the line k is \frac{-3}{2}

We know that : If two lines are perpendicular, then the product of slopes of the two lines should be equal to -1

⇒ Slope of line k × Slope of line perpendicular to k = -1

⇒ \frac{-3}{2} \times Slope\;of\;line\;perpendicular\;to\;line\;k = -1

⇒ Slope of line perpendicular to line =  \frac{2}{3}

Option C is the Answer
