Answer:
Dimension = 30.4 x 15.2 cm
Perimeter = 91.2 cm
Explanation:
Let width of rectangle be a, so the length of rectangle = 2a.
From the figure given we have by Pythagoras theorem
[tex]76=\sqrt{a^2+(2a)^2} \\ \\ \sqrt{5} a=76\\ \\ a=15.2inch[/tex]
So, width of rectangle = 15.2 inches.
Length of rectangle = 30.4 inches.
Perimeter = 2 x (15.2 + 30.4) = 91.2 cm
Dimension = 30.4 x 15.2 cm
Perimeter = 91.2 cm
