➡➡Here is Your Answer ▪▪▪
1.Rectangle :
Area = lbPerimeter = 2(l+b)
2.Square :
Area = a×aPerimeter = 4a
3.Parallelogram
Area = l × hPerimeter = 2(l+b)
4.Triangle :
Area =b×h/2 or √s(s-a)(s-b)(s-c) where s=a+b+c/2
5.Right angle Triangle :
Area =1/2(bh)Perimeter = b+h+d
6.Isosceles right angle triangle :
Area = ½. a2Perimeter = 2a+d where d=a√2
7.Equilateral Triangle :
Area = √3. a2/4 or ½(ah) where h = √3/2Perimeter = 3a
8.Trapezium :
Area = 1/2h(a+b)Perimeter = Sum of all sides
9.Rhombus :
Area = d1 × d2/2Perimeter = 4l
10.Quadrilateral
Area =1/2 × Diagonal × (Sum of offsets)
11.Kite :
Area = d1×d2/2Perimeter = 2 × Sum on non-adjacent sides
12.Circle :
Area = πr^2 or πd^2/4Circumference = 2πr or πdArea of sector of a circle = (θπr^2 )/360
13.Frustum :
Curved surface area = πh(r1+r2)Surface area = π( r12+ h(r1+r2) + r22)
14.Cube :
Volume: V = l3Lateral surface area = 4a2Surface Area: S = 6s2Diagonal (d) = √3l
15.Cuboid :
Volume of cuboid: lbhTotal surface area = 2 (lb + bh + hl) or 6l2Length of diagonal =√(l^2+b^2+h^2)
16.Right Circular Cylinder :
Volume of Cylinder = π r2 hLateral Surface Area (LSA or CSA) = 2π r hTotal Surface Area = TSA = 2 π r (r + h)Volume of hollow cylinder = π r h(R2 – r2)
17.Right Circular cone :
Volume = 1/3 π r2hCurved surface area: CSA= π r lTotal surface area = TSA = πr(r + l )
18.Sphere
Volume: V = 4/3 πr3Surface Area: S = 4πr2
19.Hemisphere :
Volume = 2/3 π r3Curved surface area(CSA) = 2 π r2Total surface area = TSA = 3 π r2
20.Prism :
Volume = Base area x hLateral Surface area = perimeter of the base x h
21.Pyramid:
Volume of a right pyramid = (1/3) × area of the base × height.
Area of the lateral faces of a right pyramid = (1/2) × perimeter of the base x slant height.
Area of whole surface of a right pyramid = area of the lateral faces + area of the base.
22.Tetrahedron :
Area of its slant sides = 3a2√3/4Area of its whole surface = √3a2 Volume of the tetrahedron = (√2/12) a 3
23.Regular Hexagon :
Area = 3√3 a2 / 2Perimeter = 6a
