⏩ TO FIND : AREA OF THE FLOWER BED
................................................................................................................✡✡✡
⏩ HERE, a = 5 m, b = 8 m AND c = 11 m
⏩ S = a + b + c / 2
⏩S = 5 + 8 + 11 / 2
⏩ S = 24 / 2
⏩ S = 12
⏩ AREA = √s( s - a ) ( s - b )
( s - c )
⏩ AREA = √12(12 - 5) (12 - 8)
(12 - 11)
⏩ AREA = √12 × 7 × 4 × 1
⏩ AREA = √336
⏩ AREA = 18.330 cm^2 ( OR ) 4√21
