Question

a rectangular field is 24 m long and 15m wide. How many triangular flower beds each of base 3cm and altitude 4cm can be laid in this field

Answer 1

Area of triangle is 1/2(base×height) = 1/2(3×4) = 6.
Area of rectangle is length×width = 24×15 = 360.

Therefore the number of triangular beds can be laid is = 360/6 = 60.

60 triangular beds of base 3cm, altitude of 4cm can be laid in the rectangular field of length 24m and 15m
