The diagonal length = 7.07 inches.
we know that regular pentagon has 5 equilateral triangle . now ,perimeter of pentagon = 5 Xside . now,perimeter of a regular pentagon with a side length of 7.2 cm . perimeter = 7.2 X 5 =36 cm .
Length x width x height (in this case 5 x 5 x 5 =125).
20 is 5x4 so we can simplify it like this: ____ ______ / = / \/ 20 \/ 5 x 4 Also note that: ____ / = 2 \/ 4 So... ____ ____ / = / \/ 20 2 \/ 5
A square pyramid has 5 sides.
a square has 7 names

If the circle is inscribed in the square, the side length of the square is the same as the diameter of the circle which is twice its radius: → area_square = (2 × 5 in)² = 10² sq in = 100 sq in If the circle circumscribes the square, the diagonal of the square is the same as the diameter of the circle; Using Pythagoras the length of the side of the square can be calculated: → diagonal = 2 × 5 in = 10 in → side² + side² = diagonal² → 2 × side² = diagonal² → side² = diagonal² / 2 → side = diagonal / √2 → side = 10 in / √2 → area _square = (10 in / √2)² = 100 sq in / 2 = 50 sq in.
The side length of the square is about 3.54 units using Pythagoras' theorem for a right angle triangle
7.0711 (rounded)
It is a real number in the sense that it is an irrational number which can't be expressed as a fraction and its length is 5 times the square root of 2
t he older square-shaped floppy diskettes measured 15 cm on each side. What was the diagonal length of a diskette?
The length of the diagonal of a square with sides 5 is 5√2. This is because of the properties of a 45-45-90 triangle.
Using Pythagoras' theorem each side measures 3.536 units rounded to 3 decimal places
"using Pythagoras, you find the length of either of the two sides. For example, if the diagonal is = 5 Then square it = 25 Then Half it (since both of the other sides of one of the triangles are equal) = 12.5 Then Square Root it = sqrt(12.5) The length of one side is sqrt(12.5) So now you can just square it and the area is 12.5 Hope that makes sense" Actually there are steps here you don't need. Use the equation: A= (d^2)/2 Where d=diagonal length. You don't need to square root it then square it again. That would only make sense if you wanted to find the side length, but in that case all you would have to do is divide the diagonal by the square root of 2, which will also give you the side length, but in a much easier way.
find the cube root of 125(which is 5) is the length of one side do Pythagorean theorem to find the diagonal 5squared plus 5 squared=50 square root of 50=7.07106781 is diagonal
Diagonal = 5*sqrt(2) units implies that side = 5 units so that area = 5*5 = 25 square units.
