If the area and the bases of a trapezoid is known, then we can calculate its height using the formula, Area of trapezoid = ½ (a + b) h; where 'a' and 'b' are the bases and 'h' is the height. In other words, we can find the height of the trapezoid by substituting the gi...

Objective:I know how to solve trapezoid problems involving base1, base2, height and area. Given that sideb1 is parallel to sideb2 andhis the vertical height betweenb1 andb2, the area of the trapezoid is given by the formula: A=
Exclusive Definition: A trapezoid is a quadrilateral with exactly one pair of parallel sides. (By this definition, a parallelogram is not a trapezoid since it has two pairs of parallel sides.) Inclusive Definition: A trapezoid is a quadrilateral with at least one pair of parallel sides. (By ...
Calculating the area of special shapes: Parallelogram: base × height It is a formula that you use to calculate the area of a parallelogram, similar to a square or rectangle formula. Trapezoids: ½ ( side + width ) height Rhombus: ½ × d1 × d2 ...
