Luas dinding persegi Lp = 4 x p x t + ( p x l ) = 4 x 4 x 2 + (4x4 = 32 + 16 = 48 m² alas segitiga a = 1/2 x 4 = 2 luas segitiga tegak LΔ = 4 ( a x t) = 4 ( 2 x 3) = 4 ( 6 ) = 24m² luas tenda seluruhnya Ltenda = Lp + LΔ = 48 + 24 = 72 m²
Lp = 4 x p x t + ( p x l )
= 4 x 4 x 2 + (4x4
= 32 + 16
= 48 m²
alas segitiga
a = 1/2 x 4
= 2
luas segitiga tegak
LΔ = 4 ( a x t)
= 4 ( 2 x 3)
= 4 ( 6 )
= 24m²
luas tenda seluruhnya
Ltenda = Lp + LΔ
= 48 + 24
= 72 m²
jawabannya 72m²
