The formula for the area of a triangle is given by A = 0.5 * base * height, where A is the area, base is the length of the base, and height is the height of the triangle.
Plugging in the values base = 13 yards, height = 5 yards:
A = 0.5 * 13 * 5
A = 0.5 * 65
A = 32.5 square yards
Therefore, the area of the triangle with base equal to 13 yards and height equal to 5 yards is 32.5 square yards.
The correct response is:
32.5 square yards

To find the height of the triangular sandwich, you can use the formula for the area of a triangle:
A = 0.5 * base * height
Given that the base measures 4 inches and the area measures 7 square inches, you can plug those values into the formula and solve for the height:
7 = 0.5 * 4 * height
7 = 2 * height
height = 7 / 2
height = 3.5 inches
Therefore, the height of the sandwich is 3.5 inches.
The correct response is:
3.5 inches
