Question

Ketinggalan kaka, bantuu yaa

Answer 1

T = √(5^(2)cm - 4^(2)cm)
= √(25cm - 16cm)
= √(9cm) = 3cm

L alas = alas × tinggi ÷ 2
= 4cm × 3cm ÷ 2
= 12cm ÷ 2 = 6cm^(2)

Kll alas = 3cm + 4cm + 5cm
= 12cm

Lp = 2 × La + (kll alas × T)
= 2 × 6cm + (12cm × 6cm)
= 12cm^(2) + 72cm^(2)
= 84cm^(2) <d>

maaf kalo salah
