Question

HOW TO FIND THE PERIMETER ​

Answer 1

We can find Perimeter through Formula of Perimeter,

As Given.

Perimeter(Rectangle)=2(l+b)

Perimeter (Square)=l×b

So These are the formulas.

Answer 2

Answer:

You have to use this formula:

Square: P = a × 4

note: a = length of sides

Rectangle: P = (L+W) × 2

explanation: perimeter is equals to length + width × 2

Triangle: P = a + b + c

explanation: a is equals to 1 side, b is equals to base, and c is equals to the other side. Add them together and you will get the perimeter.

Pentagon: P = a × 5

explanation: a is equal to length of one side. Multiply the variable a with 5.

Hexagon: P = 6 × a

explanation: a is equal to length of one side. Multiply the variable a by 6.

Octagon: P = 8 × a

explanation: a is equal to the length of one side. Multiply the variable a by 8.

Nanogan: P = 9 × a

explanation: a is equal to the length of one side. Multiply the variable a by 9.

Decagon: P = 10 × a

explanation: a is equal to the length of the side. Multiply the variable a by 10.
