The area of the reflective material is:  284 square yards.

<h3>What is a rectangle?</h3>

A rectangle is a quadrilateral with four sides and four right-angles.

it has two lines of symmetry.

Analysis:

To find the area of the reflecting material we find the area of the following shapes: trapezium + rectangle + triangle

bigger base of trapezium = 2 + 6 + 2 = 10 yard

smaller base of trapezium = 6

length of rectangle = 18 yard

width of rectangle : 2+6+2 = 10 yard

base of triangle is =  10 yard

Area of reflective material = 1/2(6+10) + 18x10 + 1/2(10)(8) = 284 square yards

In conclusion, the area of reflective material is : 284 square yards.

The correct answer is:  [B]:  " 9.6 cm " . 
____________________________________________________________

Explanation:
____________________________________________________________

Let "FH"  = "x" ;  for which we wish to solve.

45 cm / 12 cm = 36 cm  /  "x" (in "cm") ; 

To solve for "x" ;  
 
Cross--multiply:

Note:    Given:   

" \frac{a}{b} =  \frac{c}{d} " ;  " ad = bc " ;  (b ≠ 0 ; d ≠ 0) ; 


So:  " 45x = 12 * 36 "   ; 

→  45x =  432 ; 

Divide each side of the equation by "45" ; 
     to isolate "x" on one side of the equation; & to solve for "x" ; 
 
→  45x / 45 = 432 / 45 ; 

→  x = 9.6 cm ; 
___________________________________________________________
→  which corresponds with:  
___________________________________________________________

→  Answer choice:  [B]:  " 9.6 cm " .

Answer:

{x}^{2}  + 3x

Step-by-step explanation:

1.

Area of shaded region = Area of external rectangle - Area of internal rectangle

= 4x(x + 2) - x(3x + 5) \\  = 4 {x}^{2}  + 8x - 3 {x}^{2}  - 5x \\  = 4 {x}^{2}  - 3 {x}^{2}  + 8x - 5x \\  =  {x}^{2}  + 3x \\

2.

Let the width of the rectangle be x inches.

Therefore, length of the rectangle = (x + 3) inches

A.

Area of rectangle

=(x + 3)\times x\\=x^2 + 3x\\

B.

Width of rectangle = 4 inches

Length of rectangle = 4 + 3 = 7 inches

Area of rectangle = 7*4 = 28 square inches.
