By definition of <em>surface</em> area and the <em>area</em> formulae for squares and rectangles, the <em>surface</em> area of the <em>composite</em> figure is equal to 166 square centimeters.

<h3>What is the surface area of a composite figure formed by two right prisms?</h3>

According to the image, we have a <em>composite</em> figure formed by two <em>right</em> prisms. The <em>surface</em> area of this figure is the sum of the areas of its faces, represented by squares and rectangles:

A = 2 · (4 cm) · (5 cm) + 2 · (2 cm) · (4 cm) + (2 cm) · (5 cm) + (3 cm) · (5 cm) + (5 cm)² + 4 · (3 cm) · (5 cm)

A = 166 cm²

By definition of <em>surface</em> area and the <em>area</em> formulae for squares and rectangles, the <em>surface</em> area of the <em>composite</em> figure is equal to 166 square centimeters.

Given that Z = X m W = 4x + 20 and m Y = x + 26 find the value of x for which WXYZ must be a parallelogram
umka21 [38]
<h2>Explanation:</h2>

A parallelogram is a quadrilateral where both pairs of opposite sides are parallel. We know that for any parallelogram opposite angles are also equal. Here:

\angle Z=\angle X \\ \\ \text{and this also must be true} \\ \\ \\ \angle W= \angle Y \\ \\ \\ Then: \\ \\ 4x + 20 = x + 26 \\ \\ \\ Solving \ for \ x: \\ \\ 4x-x=26-20 \\ \\ 3x=6 \\ \\ \boxed{x=2}
