tolong di jawab nomor 22 pake caranya terima kasih

L Persegi = 28 X 28
                  = 784 cm2

L Lingkaran = 22/7 X 14 X 14
                      = 22 X 2 X 14
                      = 22 X 28
                      = 616 cm2

L Segitiga = 1/2 X 26 X 28
                   = 26/2 X 28
                   = 13 X 28
                   = 364 cm2

Luas Asiran = 364 + ( 784 - 616 )
                      = 364 + 168
                      = 532 cm2
