Question 78327
<pre>
Find the length of a side of a square whose area is the same as that of a rectangle 24 cm. by 30 cm.


Find the area of the rectangle first

   Area of Rectangle = Length * width
                     = 24 * 30
                     = 720 sq cm


   Area of rectangle = Area of square
         720sq cm    = 720 sq cm


   Area of the square = s^2
            720 sq cm = s^2
        {{{ sqrt (720)}}} = s
                26.83  = s
