Suppose that you're building a shed and me to pour concrete slab to support it. you know that the slab will be 15 feet wide, 10 feet long, 6 inches deep. concrete is usually sold by the cubic yard. how many cubic yards of concrete will you need for the slab?

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
