The area of a triangle is (1/2)(base)(height). In the case of a right triangle, one leg is the length of the base and the other leg is the height.The area in this case is (1/2)(13)(2) = 13 square units.
(13x9) / 2 Length times width. Divide by 2
Triangle B The area of a triangle is the length of the base times the height divided by two. Triangle A has base 13 m and height 5 m so we have (13 * 5) / 2 = 32.5 square meters. Triangle B has base 9 m and height 8 m so we have (9 * 8) /2 = 36 square meters. Therefore Triangle B has the greater area.
The area of triangle is : 78.0
