|
Answer» Answer: Step-by-step EXPLANATION : Area of two equal CIRCLES is 2 x pi r² =>2 x 22/7 x r x r=308 =>r²=308/2 x 7/22 =>r²=49 =>r=√49=7cm,, Now, 2r = diameter of circle = length of rectangle length=14 cm radius of circle = breadth of rectangle=7 cm ∵PERIMETER of rectangle = 2(l+b) = 2(14+7) = 2 x 21 = 42cm Length =14 cm Breadth =7cm ∴The perimeter of the rectangle is 42 cm.
