If we draw perpendicular h from CD to meet AB at E, such that, it forms a right triangle, AED, then, Length of perpendicular, h = √(c2 – (a-b)2)   [By Pythagoras theorem]. To calculate the area and perimeter of trapezium, here is the formula of area and perimeter of trapezium. Step 1: Remember the formula. We know, a trapezium has exactly one pair of parallel sides and the other two sides are non-parallel. I designed this web site and wrote all the mathematical theory, online exercises, formulas and calculators. The perimeter of the trapezium is simply the sum of the lengths of its sides. A trapezoid shape is mostly used for manmade channels and the cross section of natural stream channels. A trapezium that has equal non-parallel sides and equal base angles is an isosceles trapezium. The parallel sides are the bases and another two sides are called legs of the trapezoid. It is called the midsegment. Area = ½ * (a + b) * h The trapezium is further categorised into three different types, namely. A trapezium is a 2d shape and a type of quadrilateral, which has only two parallel sides and the other two sides are non-parallel. Solution: Let x = common ratio. i.e., ∠A + ∠B + ∠C + ∠D = 360°. answer choices . 3. Trapezium is a type of quadrilateral that has at least one pair of side parallel to each other. The perpendicular distance between parallel sides is called height of trapezium. Area of a parallelogram. 0. Let the given sides be a,b,c and distance b/w parallel lines be h.
