Question: what is the formula of area of isosceles trapezium?
Answer: An isosceles trapezoid has one pair of nonparallel sides congruent. To find the area of the trapezoid, we use the formula that the area of a trapezoid is equal to 𝐴 plus 𝐵 over two times ℎ, where 𝐴 and 𝐵 are the basis and ℎ is the perpendicular height.
