The boy had to find the area and perimeter of the pentagon.
Area = 110.11 cm2
A regular pentagon has five (5) equilateral triangles within it. Find the area of each triangle (1/2bh where b is the base of the triangle or the length of a side of the pentagon, and h is the height of the triangle or the apothem of the pentagon) and multiply the area of the triangle times five (5).
If 6 is the side of a regular pentagon, the area is 61.937
Since the question does not say so, you may not assume that the pentagon is regular. One way to find the area is to select any point inside the pentagon and join it to each of the vertices. This will divide the pentagon into 5 triangles. You can then measure the sides of each triangle and thereby calculate its area. Then sum the areas of the triangles. You could also select one side in each triangle as the base and then draw and measure the perpendicular distance to the opposite vertex. That is another way to find the area of each triangle. There are other methods, too. To find the perimeter you will need to measure the length of each side of the pentagon and add these lengths together.
Oh yes, it most definitely will. They're equal.

If you mean a pentagonal prism, then find the area of the pentagon 1st. Length of 1 side x 1.7, then multiply by the height of the prism. But I dont really know the regular Pentagon volume. sorry... hope you dont hate me for that.

surface area= b x h actually no its 5(a)(s)+5(s)(h) s is side and h is height only problem i dont know what a is

A pentagon is a 2-D shape. You can't find the volume of it unless it's 3-D. The formula for the area of a pentagon has something to do with the perimeter, the number of sides, the apothem, and the number 2.
Given only the information in the question, there is no option but to measure the pentagon at the base and calculate its area.
That depends on the size of the pentagon, and whether it is regular or not. In general, you can divide the pentagon into three triangles, and calculate the area of each triangle separately.
