area of a regular triangle

An equilateral triangle and a regular hexagon have equal perimeters. What is the ratio of the area of the triangle to that of the hexagon? => 4 3 or 3 2 or 3 4 or 2 3..

ABM is an equilateral triangle. ABCD is a square and ABEFGH is a regular hexagon. Find the ratio of area enclosed in the region AHGFEBCDA to the area enclosed in the region ADCBMA. [Take a = 7 units.] => 6 3 - 4 4 or 3 3 - 2 4 - 3 or 6 3 4 - 3 or 6 3 - 4 4 - ..

Theorem: - In any triangle ABC, prove that the area of a triangle ABC is given ..

Area of a triangle - If the coordinates of the vertices of the D ABC are A(x 1 ,y 1 ), B(x 2 ,y 2 ) and C(x 3 ,y 3 ), then the area of triangle is given ..

We have already learnt in the previous class that the area of triangle whose vertices are (x 1 , y 1 ), (x 2 , y 2 ), (x 3 , y 3 ) is given by Hence area of a triangle having vertices at (x 1 , y 1 ), (x 2 , y 2 ) and (x 3 , y 3 ) is given by..

If the coordinates of the vertices of the D ABC are A(x 1 ,y 1 ), B(x 2 ,y 2 ) and C(x 3 ,y 3 ), then the area of triangle is given ..
