Question

a Wire in the shape of rectangle 40cm×22cm. if this wire is rebent in the shape of square ,what will be the measure of each side?also find which shape encloses more area.

Answer 1

4*side=( length +breadth) 4*sides=(40+22) 4*sides =2*62divided by 4 =31cm..

Answer 2

first find the area of the wire bent in the shape of rectangle.
Area of rectangle = l x b
                               = 40 x 22 cm
                               = 880 sq.cm
area of rectangle = area of square
                                           2
           880                    = a 
  square root of 880    = a
           30                      =a
