Find the area of rectangle which has length 7 cm and breadth 4 cm.

If the sides of a square are doubled, then its area:

The adjoining figure is made of two squares whose sides are $2 cm$ and $6 cm$ respectively. So, the perimeter of the figure will be:

A painting is 80 cm wide and 1.6 m long. The ratio of its length to its perimeter in the simplest form is:

If the length of a rectangle becomes half and breadth of a rectangle becomes double, then the area of the rectangle:

Find the perimeter of rectangle, if the area of a rectangle is $660 c{m}^2$ and breadth is $20 m$.
