Answer:
219.05 m²
Explanation:
Dimension of right angle triangle : 109 m and 190 m
The right angle triangle has a height of 190 m and base length of 109 m
A corner of the base from the pyramid's top is equivalent to the hypotenus of the right angle triangle :
Let :
hypotenus = c ; base = b ; height = a
Hypotenus² = opposite² + adjacent²
c² = a² + b²
c² = 190² + 109²
c² = 36100 + 11881
c² = 47981
c = sqrt(47981)
c = 219.04565
A corner of the base from the pyramid's top is 219.05 m²
