Question

A rectangle is 25 metre long and 16 metre broad. Find the side of a square whose area is equal to the area of this rectangle.​

Answer 1

Area of a rectangle = L × B

= 25 × 16 = 400

Now, the area of a square = side ^2 = 400

=

${side}^{2} = 400$

$= side \: = \sqrt{400} = 20$

Hence, the side of the square is 20 Metre.

..

Answer 2

the area of the rectangle = 25×16= 400m^2

therefore, area of square = 400m^2

side of square = (400)^1/2

= 20 m
