Fig. The base of the triangle is 12 feet, and it is also 12 feet high,what is its area? Half the height~6 feet; and 12x6 = 72 square feet find the area of a Trapezium. Note. A Trapezium is any four-sided figure that is neither a recUangle, like a square or oblong, nor a parallelogram. Rule. Join two of its opposite angles, and thus divide it into twotriangles. Measure this line, and call it the base of each triangle. Measure the perpendicular height of each triangle aboye thebase line. Hand Book of Calculations, 10 r MENSURATION. Then find the area of each triangle by the last rule; theirsum is the area of the whole Fig. find the area of a Trapezoid. Trapezoid is a trapezium having two of its sides parallel. half the sum of the two parallel sides by the per-pendicular distance between them. k ? >i
