A. Berapa tingginya ( AC ) pakai Pytagoras ya!?
B. Carilah luasnya !

Answer 1

Verified answer

A) AC = √100² - 10²
           = √10.000 - 100
           = √9.990
           = 99,94 cm

B) Luas = 1/2 x alas x tinggi
              = 1/2 x 10 x 99,94
              = 5 x 99,94
              = 499,7
              ≈ 500 cm²

Answer 2

A.t=AC =√100²-10²
           =√10.000-100
           =√9900
           = √100 x √99
          =10 x √9x11
          =10 x 3 √11
          =30√11 cm

B.Luas = 1/2 at
            =1/2 x 10 x 10√11
            = 50√11 cm²
