Answer:
275.63 mm^2
Step-by-step explanation:
The measurements of the pyramids are
Edge length: 10
Egde width: 8.66 (because 10x8.66/2 = 43.3)
Height: 9
To find the surface area, use this formula, and you will get 275.63:

Answer:
30 m²
Step-by-step explanation:
What is the area of this triangle? A=bh/2 17 m² 30 m² 60 m² 120 m² Right triangle with height labeled 12 m, base labeled 5 m, and third side labeled 13 m.
Area of a triangle = bh/2
b = Base = 5m
h = Height = 12m
Area of the triangle = 5m × 12m/2
= 60m²/2
= 30 m²
