what is perimeter and area of rhombus, pentagon and hexagon also?
Answers
The Perimeter of any figure, whether it's a circle, or a square, or a pentagon or a rhombus or anything.
It's Perimeter is always Sum of all sides
Still, the area of any figure isn't figure and for making calculations little easier we have write the perimeter as in below
The below table shows the area and perimeter of all the shapes asked.
Rhombus :-
- Area = ½ × d₁ × d₂
- Perimeter = 4 × Side
Pentagon :-
- Area = (5 ⁄ 2) × side × apothem length
- Perimeter = 5 × Side
Hexagon :-
- Area = 3√3/2 × (side)²
- Perimeter = 6 × side
Answer:
The perimeter of any shape is the sum of the lengths of its sides. As for area, if you connect the opposite corners of the rhombus with straight lines you should see four congruent right triangles, which should suggest how you can use those connecting lines (the diagonals) to find the area.
If you don’t have the diagonal lengths, then you would need the angles (or else you can’t tell this rhombus from any other with the same sides, which could have radically different areas). In that case it’s a question of whether you know the sine rule for area of a parallelogram (of which a rhombus is a special case). But given the question that you asked, I’m guessing the method with the diagonal lengths is the one you want.
