Answer:

FIND AREA OF SQUARE THEN SUBTRACT THE AREA OF 4 SECTORS FROM IT.

AREA OF SECTOR=ANGLE/360 *3.14R²

I WANT U TO DO ON UR OWN

angle= 90

so 4*1/4*pi$49

=154 is the area of 4 sectors.

so area of square=14²=196

area of shaded region=196-154=42

area of the square=14²

area of 1 quadrant=1/4×πr²

1/4×22/7×7

area of 4 quadrants=4×1/4×22/7×7×7

= 22/7×7×7

=22×7

=154cm²
