There is no simple formula and, in any case, the answer will depend on what information about the trapezoid is given.
A trapezoid has one height: vertical measurement from top to bottom, and two bases: horizontal measurement on top and horizontal measurement on bottom. To find the area, you add the two bases together, multiply that by the height, and then divide by 2.
by the formula of ---A*b
Area in square units = 0.5*(sum of parallel sides)*height
To find the circumradius of an isosceles triangle, the formula is:1/8[(a^2/h)+4h]in which h is the height of the triangle and a is the base of the triangle.
For all triangles: area = 1/2 * base * height

You need to measure them.
For all triangles: area = 1/2 * base * height
Just use the formula (Base x Height '/. 2) to get the area
To calculate the perimeter of an isosceles triangle, you add the lengths of all three sides. If the lengths of the two equal sides are each ( a ) and the base is ( b ), the formula is ( P = 2a + b ). Simply substitute the values of ( a ) and ( b ) into the formula to find the perimeter.
To solve for the dimensions of an isosceles trapezoid when the median is given, first recall that the median (or midsegment) of an isosceles trapezoid is the average of the lengths of the two parallel bases. If the median is ( m ) and the lengths of the bases are ( a ) and ( b ), then the relationship can be expressed as ( m = \frac{a + b}{2} ). You can use this equation to find one base if the other is known, or to establish relationships between the bases if additional information is provided. Additionally, you can apply properties of the trapezoid and the Pythagorean theorem to find heights or side lengths if needed.
Add together the lengths of its four sides.
Each of its parallel sides is classed as a base
The general formula to calculate area of a trapezoid ( and an isosceles trapezoid) is:AREA=(Sum of parallel sides)(Distance between parallel sides)/2. And if you find this formula difficult, calculate separately the area of two right angled triangles and a rectangles. For more details, contact at saqibahmad81@yahoo.com
