In a woodworking class, you need to make five triangles out of plywood. each triangle has a height of 6 inches and a base of 14 inches. which equation can you use to solve for the total amount of plywood you will need?

The area of a triangle can be calculated through the equation,
                            A = bh / 2
where A is area, b is base, and h is height. 
Substituting the known values from the given above to the equation
                            A = (14 in)(6 in) / 2 = 42 in²
Since, there are five of these triangles, the total area is,
                            total area = 5(42 in²) = 210 in²
Thus, the total area of the plywood needed is 210 in².
