Fun fact : all are watching this for their final exams 😂😂

Area and Perimeter of Shapes
Area:
SQUARE=SIDE×SIDE
RECTANGLE=L×B
PARALLELOGRAM= BASE × HEIGHT
TRIANGLE=½× BASE×HEIGHT
CIRCLE=πR²
PERIMETER:
SQUARE=4×SIDE
RECTANGLE=2×(l+b)
CIRCLE=2πR
SEMICIRCLE=diameter+πR
FOR ALL MY FRIENDS 😊

Summary of the video 👇🏻
Perimeter of a square = 4× side
Perimeter of a rectangle = 2( l + b )
Area of a square = side × side
Area of a rectangle = l × b
Area of a Parallelogram = B × H
Area of a triangle = ½ × B × H
Circumference of a circle = 2 π r
Area of a circle = π r²
Perimeter of semi circle = D + π r
Area of parts = Example Area of (ABCD) - (PQRS)

All the best for your exams 👍🏻

Notes:


perimeter of square: 4 x side
area of square: side x side

perimeter of rectangle: 2 (l+b)
area of rectangle: l x b

perimeter of circle: 2*pi*r
area of circle: *pi*r^2

perimeter of semi-circle: d + *pi*r
area of parallelogram: b x h
area of triangle: 1/2 (b x h)

area of parts: area of figure - unshaded parts

Thank You Ma'am for the lesson!!

I don't see any teacher like you . Your teaching is best. Heads of you.

[uppensai]

This is better than going to school our math teacher doesn’t even teach anything when we start a new chapter she just suddenly starts and everyone knows how to do it somehow
