area of shaded region = area of triangle - area of three arcs
= (1/2 x b x h) - {( ∠A/360 x ² ) + ( ∠B/360 x ² ) + ( ∠C/360 x ² )}
= (1/2 x 48 x 14) - {² (∠A+∠B+∠C)/360}
=(48 X 7) - { 3.14 x (5)² x (180/360)}
= 336 - ( 3.14 x 25 x 1/2 )
= 336 - ( 1.57 x 25 )
= 336 - 39.25
= 296.75
= (1/2 x b x h) - {( ∠A/360 x ² ) + ( ∠B/360 x ² ) + ( ∠C/360 x ² )}
