A quadrant is just one forth part of a circle...... Whenever we need to find area of a quadrant it is the same as that of the sector having theta 90°.......... According to question, Circumference = 22units...... 2 × 22/7 × r = 22........... r = 7/2units....... Area of quadrant = theta/ 360° × 22/7 × r^2........... = 90°/360° × 22/7 × 7/2 × 7/2......... = 77/8.......... = 9.62 units^2
