Question

ABCD is a rectangle in which length is double of its breadth ,two eqilataral triangle are drawn on each length ,find the ratio of their areas.

Answer 1

ANSWER :-
According the question,we get Length= double of breadth, that means ,l=2b,let abcd be the rectangle.AB= CD=2b.AD=BC=b equilateral triangles are drawn on l and b,for triangle drawn on l, all sides=2b, for triangle drawn on b, all sides= b, we know that equilateral triangles are similar therefore ratio of area of triangles = square of ratio of sides=2b/b, the whole square= 4/1, therefore the ratio is 4:1.

Hope it makes you clear.
