The Answer is Triangular Prism.
Mean is just another word for average. To find the average of something you must add up all values and divide by the number of values in the set.
W= width
To find dimensions 3x-5 + x + x + 3x-5 = 150
Perimeter = 2l + 2w so that’s why we repeated
So now we simplify
8x - 10 = 150
Add 10 to both sides
160 = 8x
Divide 8 from both sides
X=20
So width is 20 inches. and to find length it is:
3(20)-5 = 60 -5
=55
Length = 55 inches
