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.

Teach a child area of triangle without formula?
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.
Can you give me an example of an area of an obtuse angle?
Right triangle square rectangles
There are two rectangles a triangle and half a circle find the total area?
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.
What is the formula to figure out square foot?
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.
Formua for area of a triangle?
Area of a triangle: 0.5*base*perpendicular height
