31.5 sq. in.
18 square inches
The first is clearly not a suitable triangle.
If "length" means "length of side to which the height of 14 inches is perpendicular", area = (1/2)(14)(16) = 112 square inches. (These dimensionss of a triangle are more commonly called "base" and "altitude" respectively.)
The area of every triangle is 1/2 the product of (length of the base) x (the height).Armed with that information, you can easily calculate the area of your triangle, andany others that you might encounter in the future. Go forth and multiply !
Its height is 8 inches
The length of a triangle with a height of 12 inches and an area of 18 square inches is 3 inches, since area is 1/2 * base * height. Therefore, 2 * area divided by height = 2 * 18 /12 = 3
48in2. To find the area of any triangle - you divide the length of the base by 2, then multiply that figure by the height.
18 square inches
What is 12 in ? And what is 16 in ? ? Are they the lengths of two sides of the triangle ? Are they the length of one side and the height of the triangle ? The area of any triangle is 1/2 of the product of (length of its base) x (its height).
The first is clearly not a suitable triangle.
-- Measure the length of the base, in inches. -- Measure the height of the triangle, in inches. -- Multiply the two numbers and take 1/2 of the product. 1/2 of the product is the area of the triangle, in square inches.
If "length" means "length of side to which the height of 14 inches is perpendicular", area = (1/2)(14)(16) = 112 square inches. (These dimensionss of a triangle are more commonly called "base" and "altitude" respectively.)
