Jawaban: #1:
21. area square = area rectangle
                          =l x w
                          =36 x 25 
                          =900 cm²

    area square =s² = 900 cm²
                           s=√900
                             = 30 cm
 so length of side square = 30 cm

22.circumference square = 4 x 30 = 120 cm
     circumference rectangle = 2 ( l+w ) = 2 ( 36+25 ) = 2 x 61 =122 cm
      so lace she needs = 120+122 = 142 cm
