Question

A pavement of width 1 meter is laid around a square park having length 20 meter what is the total area of pavement?

Answer 1

Hi friend,

Here is your answer,
______________________________________________________________
Square park has side of 20m.

After adding the length of pavement the side becomes 22m.
Area of pavement = 22² - 20²
                             = 484 - 400
                             = 84m²
