Answer 1

Here is your answer
Area of Rectangle = L × B
= 16 × 12
= 192 sq.cm
Radius of quarter circle is 7 cm
There are four quarter circle
So
Area of four quarter circle is = 4 × πr^2/4
= πr^2
$= \frac{22}{7} \times 7 {}^{2} \\ = 22 \times 7 \\ = 154 \: sq \: cm$
Therefore Area of UNSHADED portion is
= 192 - 154
= 38 sq. cm
