No because a regular polygon is a two-dimensional shape with straight sides that all have equal length. A regular decagon is a 10-sided regular polygon. As it turns out, there are only three regular polygons that can be used to tessellate the plane: regular triangles, regular quadrilaterals, and regular hexagons.

Answer:

You need to buy 13 quarts of paint

Step-by-step explanation:

The correct question is

A movable section of stage has the shape of a right triangle. You need to apply 2 coats of paint (Assume you will not paint the bottom of the ramp). The paint covers approximately 80 square feet per quart. How many quarts of paint do you need to buy?

The picture of the question in the attached figure

step 1

we know that

The figure show a triangular prism

The surface area of the triangular prism is given by

$SA=2B+PL-(14)(19.5)$ ----> (the area of the bottom is not included)
