Question

a rectangular field is 48 cm long and 20 m wide. how many right triangular flower bed ,whose sides containing the right angle measure 12 m and 5 cm can be made.

Answer 1

AREA OF RECTANGLE=LENGTH×BREATH
    LENGTH=48 cm
   BREATH=20×100cm=2000cm
         AREA=48×200
                  =96000cm²
AREA OF TRIANGLE=HEIGHT×BASE×1/2
HERE, BASE=12×100cm=1200cm
           HEIGHT=5CM
AREA=1200×5×1/2
         =6000/2
         =3000cm²
AREA OF RECTANGLE/AREA OF TRIANGLE=NO. OF FLOWER BED
                                            =96000/3000
                                            =96/3
                                            =32 FLOWER BED
