Explanation:
#"the area of a triangle is found using the formula"#
#•" area (A)"=1/2bh#
#"where b is the base and h the perpendicular height"#
#"multiply both sides of the formula by 2"#
#rArr2A=cancel(2)xx1/cancel(2)bh#
#rArrbh=2A#
#"divide both sides by h"#
#(cancel(h) b)/cancel(h)=(2A)/h#
#rArrb=(2A)/h#
#"substitute the values gives b"#
#b=(2xx256.5)/27=19" inches"#
