Ответ:
169.6 units squared
Step-by-step explanation:
The lateral area is basically the surface area of the figure minus the base area.
Here, we just need to find the area of each triangular side and add those together. The triangles we have are:
1. Δ with base 12 and height 13.1
2. Δ with base 6.5 and height 14
3. Δ with base 6.5 and height 14
The area of a triangle is denoted by:
, where b is the base and h is the height. The areas are thus:
1.
units squared
2.
units squared
3.
unit squared
Add these together:
78.6 + 45.5 + 45.5 = 169.6 units squared
Ответ:
169.6 units²
Step-by-step explanation:
Lateral surface area of a pyramid is the sum of all faces except the base
(½×12×13.1) + (½×6.5×15) + (½×6.5×14)
= 78.6 + 45.5 + 45.5
= 169.6
