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).

To find the area, first divide the shape into regular, simple shapes. Then use formulas to find the area of the smaller, regular shapes. Lastly, add up all the smaller areas to find the area of the original shape.

It can be divided into 5 equal triangles so find the area of a triangle and then times it by 5. Area of a triangle is 0.5 times base times perpendicular height.

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.

First you find the area of the base which is a pentagon. Then you multiply it by the height. So base times height equals volume.

To find the area of a regular pentagon, you can use the formula area is equal to n multiplied by r raised to the second power time tan pi/n, where n is the number of sides or 5 and r is the radius. Using the formula, the area is 232.33 square meters.

Volume is Area of the Base times the Height of the Prism. To find the area of a Regular Pentagon, you use the formula (1/2)*Perimeter*Length of Apothem.

you can't do this because it is a 2-D figure in order to find Surface Area you need a 3-D figure but you can find the area of a pentagon

regular pentagon has five sides,perimeter=140*5=700cm

Oh yes, it most definitely will. They're equal.

Multiply the known length by 5, because the sides are all the same length on a regular pentagon and a pentagon has 5 sides.

The boy had to find the area and perimeter of the pentagon.

Basically, the same as the volume of any other pyramid: the volume is (1/3) x base x height. The "base" refers to the area of the base; for instance, if the base is a regular pentagon, use the formula for a regular pentagon.
