HOPE IT WILL HELP YOU.

Step-by-step explanation:

4×AREA OF SQUARE - 4×AREA OF QUADRANT

=(4×(20)^2-4×1/4 × π 20×20) cm square.

=(4×400-1×3.14×400)cm square.

= (1600-314×4)cm square.

=(1600-1256)cm square.

=344 cm square.

THANKS.

Answer 2

Answer:

4×area of square - 4xarea of quadrant

= (4 × (20) ^ 2-4 * 1/4 × π 20 × 20) cm²

= (4x400-1×3.14×400)cm²

(1600-314x4)cm²

=(1600-1256)cm²

=344 cm²
