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:
The value of x is 26.
Step-by-step explanation:
In a triangle, the total angles is 180°. In order to find the value of x, you have to add up all the angles in terms of x and make it equals to 180°
2x + 3x + 50 = 180
5x + 50 = 180
5x = 180 - 50
5x = 130
x = 130 ÷ 5
x = 26
0.134 = 134/1000 = 67/500
