For Last minute preparation just do revision of these formulas

Area |
Perimeter |
Volume |
| Square | l x l | 4l | |
| Rectangle | l x b | 2( l + b ) | |
| Triangle | ½ x base x height | l + l + l | |
| Circle | π r2 | 2 π r | |
| Parallelogram | base x height | ||
| Sector of a Circle | π r2 x a°/360° | 2 π r x a°/360° | |
| Rectangular Solid | 2(lb + bh + lh) | l x b x h | |
| Cylinder | π r2 + 2 π r h | π r2 h |
Where l = length, b = breadth , r = radius , a = angle of sector of circle, h =height
1. Area of Square = l x l = l²
Perimeter of Sqaure = 4 x l
2. Area of Rectangle = l x b
Perimeter of Rectangle = 2 (l + b) 
3. Area of Circle = π r2
Perimeter of Circle = Circumference of Circle = 2 π r
4. Area of Sector POQ of Circle
Length of arc PQ of a circle
5. Area of Triangle = ½ x b x h
Perimeter of Triangle = l1 + l2 + l3
6. Surface area of a Rectangular Solid = 2 ( lb + bh + lh)
Volume of Rectangular Solid = l x b x h
7. Surface area of Cylinder = 2 π r2 + 2 π r h
Volume of Cylinder = π x r² x h
