hitunglah luas bahan yang diperlukan untuk membuat tenda tersebut

p = 6 m
l = 4 m
tp = 2m
ts = 1,5 m
sm = akar [(ts)^2 + (1/2×l)^2]
= akar [1,5^2 + (1/2×4)^2]
= akar [1,5^2 + 2^2]
= akar [2,25 + 4]
= akar 6,25
= 2,5 m
L = [L prisma] + [L prisma segitiga]
= [p×l + 2×p×tp + 2×l×tp] +
[2×1/2×l×ts + 2×p×sm]
= [6×4 + 2×6×2 + 2×4×2] +
[2×1/2×4×1,5 + 2×6×2,5]
= [24 +24 +16] + [6 + 30]
= 64 + 36
= 100 m^2
biaya = L × Rp 15.000,00
= 100 × Rp 15.000,00
= Rp 1.500.000,00
