The area of a triangle is expressed using the formula A=(1/2)(bh)
Where A is area
Where B is length of the base of the triangle.
Where H is the height of the triangle.
The area of a rectangle is A=BH,
Where B is the length of the base of the rectangle.
Where H is the height of the rectangle.
Because a triangle, essentially, is a half of a rectangle, you find the area of the whole rectangle that the triangle comes from, then divide that in half.
You will have to use a formula, but this can easily be derived for the special case of a right triangle. If you divide a rectangle by a diagonal, you divide it into two congruent triangles, therefore, the triangle has half the area of the rectangle, that is, 1/2 times base times height.
Right triangle square rectangles
The answers depend on what measures are available for the rectangles (sides, diagonals), for the triangle (3 sides, 2 sides and included angle, one side and 2 angles), and for the circle (radius, perimeter). In each case the formula to be used will be different.
LxW multiply length by width. For triangle divide by two. Most irregular shapes can be broken down into triangle and rectangles. Add the pieces This question is impossible to answer, since the shape that you are calculating the area of is not mentioned.
Area of a triangle: 0.5*base*perpendicular height
The formula to calculate the area of a triangle is A = 1/2 * base * height, where A represents the area, the base is the length of the triangle's base, and the height is the perpendicular distance from the base to the opposite vertex. This formula is derived from the fact that the area of a triangle is half the product of its base and height. By plugging in the values for the base and height into the formula, you can easily determine the area of the triangle.
Heron's formula can be derived by dividing a triangle into two right triangles and applying the Pythagorean theorem to each. This allows for the expression of the area of a triangle in terms of its side lengths, which eventually leads to Heron's formula.
Divide polygon into rectangles, then use area formula for rectangle: Area = (high a + high b) / 2 x length c If polygon contains triangle, then triangle can be considered as rectangle with one of its side length is close to zero.

depends on the shape, if its a square the formula is LW, a rectangle is the same. For a triangle the formula is Lx1/2W. for a trapezium split it into triangles and rectangles and work out the areas before adding them together. for a circle i think its pixrsquared
Area of Equilateral Triangle A= S2 * (Root 3)/4, where A= Area of the triangle S= Side of the triangle.
The title of the formula is "Formula for the Area of a Triangle". No discrimination is expressed or implied.
Area of a triangle = 0.5*base*perpendicular height Area of a parallelogram = base*perpendicular height
That will depend on their dimensions which have not been given.
