5.2.3 Solving Real Life Problems involving Square Root

We solve real life problems involving square roots by using the
method of finding the square root.

Example 1: The area of a rectangular park is equal to another square

shaped park. Find the length of a square shaped park if the length

and breadth of the rectangular park are 81m and 25m respectively.

Solution:
Area of the rectangular park = length x breadth

= 81m x 25m = 2025 m2

As we know that,

Area of square shaped park = Area of rectangular park

Length of side =

=

=
