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.
