Trapezium is a two dimensional (2D) geometric shape. In this, one pair of opposite sides are parallel but not equal. The base angles of the isosceles trapezium are equal. Hence, the two non parallel sides are equal.
Area: This is the half of sum of parallel sides * distance between the parallel sides ie: (Sum of parallel sides * height) / 2 = (a+b)*h/2
Perimeter: Perimeter of an isosceles trapezium is the sum of all sides ie: a+b+c+d
Meter (m): is the base unit of length in the International System of Units (SI). Metre is defined as the distance travelled by light in a specific fraction (1299 792 458) of a second.
Other SI units: are millimeter (mm) ie 1/1000 of m, centimeter (cm) which is 1/100 of m and kilometer (km) which is equal to 1000m.
Other English units of measure of distance are:
Mile: An English unit of length, it is equal to 1609 meters (m).
Yard: It is equal to 0.9144 meters (m).
Foot: It is equal to 0.3048 meters (m).
