Answer:To do so, she makes the measurements shown in the figure below.
Step-by-step explanation:
Answer:
x = 11
Step-by-step explanation:
2(x - 5) = 12 ← divide both sides by 2

Multiply both 711.9 and 8.4 by 10 which will remove the decimal point.
and make the calculation much more easier
the required answer would be 84.75
To find the surface are of the base: 8 * 8 = 64/2(becasue its a triangle not a square base) = 32.
To find the surface are of the 3 other faces, 12 * 8 = 96/2 = 48 * 3(for the 3 sides) = 144.
The entire surface area is 176.
