The following word problem is for practicing the application of measurements of ordinary shaped objects.

Example 1:

What is the surface are of a triangle with a base of 12 feet and a distance of 24 feet from the base to the tip?

To solve for the area of a triangle, take into consideration that a rectangle with the dimensions of the base times the height of the triangle is twice the area of the triangle. So, find the area of the rectangle with the given dimensions and divide that by 2 to get the area of the triangle.

                    

12 × 24 ÷ 2 = area of the triangle
12 × 24 ÷ 2 = 144

The area of the triangle is 144 square feet.
