The perimeter of a rhombus is 240 m and the distance between any two parallel sides is 20 m. The area of the rhombus in sq.m. is
Let the side of the rhombus = $$a$$ m
=> Perimeter = $$4a=240$$
=> $$a=\frac{240}{4}=60$$ m
Height of rhombus = $$h=20$$ m
$$\therefore$$ Area of rhombus = $$a \times h$$
= $$60 \times 20=1200$$ $$m^2$$
