Area of a triangle with base (b) and height (h) is

Area of the square with side-length ‘a’ is

Area of a circle with radius ‘r’ is:

1 cm is equal to how many millimeters?

Surface area of cube of edge ‘a’ is:

Volume of a cuboid of length (l), width (w) and height (h) is:

1 litre is equal to how many cubic centimeters?

The perimeter of a rectangle with length (l) and width (w) is:

If the length and breadth of a rectangle are 15cm and 10cm, respectively, then its area is:

Length = 15 cm

And breadth = 10 cm

Area of rectangle = Length x breadth

= 15 x 10

= 150 sq.cm

All six faces of a cube are:
