Question

which expression can be used to find the area of the composite figure?
○ 4x
○ 2x+2x²
○ x²+2x
○ 3x²

Explanation:

Answer:

D. \( 3x^2 \)

(Note: To determine this, analyze the composite figure: it consists of a rectangle and two triangles. The rectangle has dimensions \( 2x \times x \) (area \( 2x^2 \)), and each triangle has base \( x \) and height \( x \), so two triangles have area \( 2 \times \frac{1}{2}x \times x = x^2 \). Total area: \( 2x^2 + x^2 = 3x^2 \).)
