The answer is 282 square units.
The surface area (SA) of the sum of the area of its base (A1) and 4 areas (A2) of the slant side. It is 4 because it is the square pyramid and it has 4 slant sides.
SA = A1 + 4A2
The area of the base (A1) is the area of the square with side a:
A1 = a²
The area of the slant area (A2) is of the square pyramid with side a and slant height s is:
A2 = a · s /2
So, it is known:
a = 10 u
s = 9.1 u
Therefore:
SA = A1 + 4A2 = a² + 4 · a · s /2 = a² + 2 · a · s = 10² + 2 · 10 · 9.1 = 100 + 182 = 282 u²
Answer:
In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.
So as we see here, they all look the same. But I can see that it says only ONE of the PAIRS of triangles is congruent.
What I can tell is that
Number 1 and 3 are probably congruent since they both have the same shape, and size.
