Answer :
The area of the whole square ABCD \( = \ 14^2 \ = \ 196 \)cm2
The sum of the area of the four quadrants at the four corners of the square
= The area of a circle of radius 7cm
\(= \ \pi(7)^2 \ = \ \frac{22}{7} \ × \ 49 \ = \ 154 \) cm2
Area of the shaded portion = The area of the square ABCD - The sum of the area of four quadrants at the four corners of the square
\(= \ 196 \ - \ 154 \ = \ 42 \) cm2
