On the webpage "area and perimeter formula for all shapes" we are going to see formula for each and every shapes in math.

What is perimeter?

**The continuous line forming the boundary of a closed geometrical figure.**

**What is area?**

**The extent or measurement of a surface or piece of land.**

**AREA AND PERIMETER OF SQUARE**

Area of square = a²

Perimeter of square = 4a

here "a" stands for side length of square.

Next we are going to see a formula for the next shape rectangle of the topic "area and perimeter formula for all shapes"

**AREA AND PERIMETER OF RECTANGLE**

Area of rectangle = L x W

Perimeter of rectangle = 2(l + w)

Here L and w represents length and width of rectangle.

Next we are going to see a formula related to equilateral triangle of the topic area and perimeter formula for all shapes

Area of Equilateral triangle = (√3/4) a²

Perimeter of Equilateral triangle = 3a

Here "a" represents side length of triangle.

**Example problems on equilateral triangle**

**Next we are going to see a formula related to scalane triangle of the topic area and perimeter formula for all shapes**

Area of scalene triangle = √s(s-a)(s-b)(s-c)

Perimeter of scalene triangle = a + b + c

here "s = (a + b + c)/2"

Example problems on scalene triangle

Next we are going to see a formula related to quadrilateral of the topic area and perimeter formula for all shapes

Area of quadrilateral =(1/2) x d x (h₁+h₂)

Perimeter of quadrilateral = Sum of all four sides

Example problems of area of quadrilateral

Next we are going to see formula related to parallelogram of the topic area and perimeter formula for all shapes

Area of parallelogram = b x h

Perimeter of quadrilateral = Sum of all four sides

Example problems of area of parallelogram

Example problems of perimeter of parallelogram

Area of circle = Π r ²

Circumference of circle = 2 Π r

Example problems of area of circle

Example problems of circumference of circle

Area of Semi circle= (1/2) Π r²

Perimeter of semi circle = (Π+2)r

Example problems on semi circle

**AREA AND PERIMETER OF QUADRANT**

Area of quadrant = (1/4) Π r²

Perimeter of quadrant = [(Π/2) + 2] r

Area of the sector = (θ/360) x Π r ² square units

(or) Area of the sector = (1/2) x l r square units

Length of arc = (θ/360) x 2Πr

Perimeter of sector = L + 2r

Perimeter of sector worksheets

Area of sector worksheetCurved surface area of cube = 4a²

Total surface area = 6a²

Volume of cube = a³

Curved surface area of cube = 2h (L + b)

Total surface area = 2(Lb + bh + hL)

Volume of cuboid = L x b x h

Here "L" "b" and "h" stands for length,breadth and height respectively.

Curved surface area = 2 Π r h

Total surface area = 2 Π r (h + r)

Volume = Π r² h

r-radius , h - height

Curved surface area= 2Π h (R+r)

Total surface area = 2 Π (R + r) (R - r + h)

Volume = Π h (R² - r²)

Curved surface area practice Worksheets1

Curved surface area practice Worksheets2

Curved Surface area = Π r L

Total surface area = Π r (L + r)

Volume = (1/3) Π r²h

L² = r² + h²

Examples of cone

Curved Surface area = 4 Π r²

Volume = (4/3) Π r³

Curved Surface area of hemisphere = 2 Π r²

Total Surface area of hemisphere = 3Πr²

Volume = (2/3) Π r³

Curved Surface area = 2 Π (R² + r²)

Total Surface area = Π (3 R² + r²)

Volume = (2/3) Π (R³ - r³)
