area of rectangle=length*breadth

area of square=side*side

area of circle=π r 2

area of parallelogram= base*height

area of triangle=1/2* base*height

perimeter of rectangle=2*(length+breadth)

perimeter of square=4*side

Circumference of circle = 2π r

Area of square- s*s

rectangle- l*b

parallelogram- b*h

triangle- half(1/2)*b*h

circle-πr 2

Perimeter of square- s*4

rectangle-2(l+b)

triangle- s+s+s

Circumference of circle-2π r

Rest i will give tomorrow!

Area of rhombus-(1/2*product of diagonals)

Area ofright angle-(1/2*product of legs)

Area ofequilateral triangle with side a-(sqrt of3/4*a*a) (note:sqrt is square root and here sqrt is of 3 not 3/4)

Area ofisoceles triangle with base b and side a-1/2*b*sqrt a*a-b*b/4 (note:here sqrt is on whole a*a*-b*b/4)

Area of four walls of a room- [2(l+b)*h]

Hope it helps!
