an electronics company is designing a watch with a face that is in the shape of a hexagon and two congruent trapezoids attached.
nalin [4]

The total area of the face of the watch to the nearest tenth of a square centimemter is 9.0 cm²

Since an electronics company is designing a watch with a face that is in the shape of a hexagon and two congruent trapezoids attached. The heights of the trapezoids and the apothem of the hexagon measure 2 centimeters each, and the length of the shorter base of each trapezoid is 1.5 centimeters, the radii of the hexagon, and the base of the trapezoid form a triangle of

  • height, h = apothem of the hexagon = 2 cm and
  • base, b = length of shorter base of trapezoid.
<h3>Area of the triangle</h3>

So, the area of this triangle is A = 1/2bh

= 1/2 × 1. 5 cm × 2 cm

= 1.5 cm × 1 cm

= 1.5 cm²

<h3>Area of the hexagon</h3>

Since there are 6 of such triangles in the hexagon, the area of the hexagon, A' = 6A

= 6 × 1.5 cm²

= 9.0 cm²

So, the total area of the face of the watch to the nearest tenth of a square centimemter is 9.0 cm²

Please help me!
Zigmanuir [339]

Answer:

s = 14

Step-by-step explanation:

Step 1: Combine like terms.

  • (\frac{2}{3}s + \frac{5}{6}s) = 21
  • (\frac{4}{6}s + \frac{5}{6}s) = 21
  • \frac{9}{6}s = 21
  • \frac{3}{2}s=21

Step 2: Multiply both sides by 2/3.

  • \frac{3}{2}s * \frac{2}{3} = 21 * \frac{2}{3}
  • s = \frac{42}{3}
  • s = 14
