Answer this question for 25 points and

  64 cm²

Step-by-step explanation:

Suppose the original paper was x cm on a side. Then the original perimeter was 4x.

When the square is folded in half, two of the sides are now x/2, so the perimeter is ...

  x + x/2 + x + x/2 = 3x

If 3x = 24 cm, then x = 8 cm.

The area of the original paper is ...

  A = x² = (8 cm)² = 64 cm²

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.
