2) Triangle: Area and Perimeter

Perimeter = a + b + c

s = (a + b + c)/2

Area = √(s(s-a)(s-b)(s-c))

Area = (1/2) × base × height

base = (2 × area)/height

3) Rectangle and Square

Perimeter of rectangle = 2(l+b)

Area of rectangle = l × b

Diagonal of rectangle = √(l² + b²)

Perimeter of square = 4 × side

Area of square = side²

4) Trapezium

Area of trapezium = (1/2) × (a+b) × h

h = (2 × area)/(a+b)

a+b = (2 × area)/h
