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:
"
" ; " 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 ;

Answer:
Step-by-step explanation:
1.
Area of shaded region = Area of external rectangle - Area of internal rectangle
2.
Let the width of the rectangle be x inches.
Therefore, length of the rectangle = (x + 3) inches
A.
Area of rectangle
B.
Width of rectangle = 4 inches
Length of rectangle = 4 + 3 = 7 inches
Area of rectangle = 7*4 = 28 square inches.
