Sam wants to build a table with that triangular top. If that tabletop has a height of 4 feet and a base of 3.5 feet, what is the area of this triangular surface
A = 1/2 * b * h
To find the area of a triangular surface, you can use the formula for the area of a triangle:
Area = 1/2 * base * height
In this case, the base of the triangular top is 3.5 feet and the height is 4 feet. Plugging these values into the formula, we get:
Area = 1/2 * 3.5 feet * 4 feet
To calculate this, we multiply 1/2 by 3.5 to get 1.75 and then multiply that by 4 to get:
Area = 1.75 feet * 4 feet
Multiplying 1.75 by 4 gives us:
Area = 7 square feet
Therefore, the area of this triangular surface is 7 square feet.
