Answer 2

Question :

• Perimeter of Triangle
• Area of Rectangle
• Perimeter of Square
• Area of Circle
• Perimeter of Parallelogram

To find :

• We have to answer the formula's of the following

Solution :

Perimeter of Triangle :-

There three types of Triangle Equilateral, Scalene and Isosceles so we will write the formula of the three

Perimeter of Equilateral Triangle $\leadsto$ 3 × Side

Perimeter of Scalene Triangle $\leadsto$ Sum of the Length of all sides

Perimeter of Isosceles Triangle $\leadsto$ Sum of the Length of all sides

Area of Rectangle $\leadsto$ Length × Breadth

Perimeter of Square $\leadsto$ 4 × Side

Area of circle $\leadsto$ $\sf\pi r^{2}$

Perimeter of Parallelogram $\leadsto$ 2 × (a + b)

In the Perimeter of Parallelogram, "a" means Side and "b" means Base
