Heron's formula was developed by Heron of Alexandria in 60 CE. Formula determines area of triangles using only side lengths. Formula uses semi-perimeter (s) equal to perimeter divided by 2
Triangle area is space covered by triangle in 2D coordinate plane. Formula uses coordinates (x1,y1), (x2,y2), and (x3,y3) of triangle vertices. Area formula is (1/2) |x1(y2 − y3) + x2(y3 − y1) + x3(y1 − y2)|
Heron's formula calculates triangle area using three side lengths and semiperimeter. Formula named after first-century engineer Heron of Alexandria. Works for both integer and real triangle sides
Area is the total space occupied by a 2-D shape. Triangle area formula: A = 1/2bh or A = bh². Triangle area equals half the area of the rectangle it's inscribed in
Area equals half base multiplied by height. Base is one side, height is perpendicular to base. Height can be found by drawing perpendicular line from base
Triangle area is enclosed space occupied by three connected straight lines. Area formula: A = 1/2 × base × height. Final answer must be in square units (cm², m², mm²)
