Answer 2

s= 50 m

Area of square = s² = 50² = 2500 m²

radius of quadrant QRC = s/2 = 50/2 = 25 m [ given R and Q are mid points of BC and RC]

area of quadrant = πr²/4 = π 25²/4 = 625π/4 m²

similarly , radius of other quadrants is 25 m so their area is also equal.

area of 4 quadrants = 4× 625π/4

= 625π

Area of shaded region = area of sq. - area of quadrants

= 2500 - 625π

= 625 ( 4 - π)

= 625 ( 4- 22/7)

= 625 ( 4 - 3.14)

= 625 × 0.86

= 537.5 m²
