Answer:
5.47 x 10^3
Step-by-step explanation:
Answer:
504
Step-by-step explanation:
The area of the base is 14 x 14 which is 196
The area of one triangle is 1/2 x base length x height which is:
1/2 x 14 x 11 = 77
So the area of one triangle is 77. The area of all the triangles is the same and there are 4 triangles.
So the surface area is
196 + 77 + 77 + 77 + 77 = 504

<em>Hence, from the list of given options, the correct answer is 170</em>
A = bh
A = 20(12)
A = 120
Area of the computer is 120
b would be 20
and the h would be 12
b = base
h = height
