Answer:
the length should be 28.5 cm.
Step-by-step explanation:
i used the equation 2L+2W=P (or L+L+W+W=P)
(length + length +width + width = perimeter)
I plugged the given information into this equation so i had:
2L+(2L-14)=86
then i solved for L
(this is what that work would look like if you need it):
2L + 2(L - 14) = 86
1. distribute the 2 in 2(L-14):
2L + 2L - 28 = 86
2. combine like terms:
4L - 28 = 86
3. add 28 to both sides:
4L = 114
4. divide both sides by 4
L = 28.5
hope this helped :)

Step-by-step explanation:
Surface area of triangular prism = bh + L(s1 + s2 + s3)
Where,
b = 3
h = 4
L = 3.5
s1 = 3
s2 = 4
s3 = 5
Plug in the values into the equation
Area of the triangular prism = 3*4 + 3.5(3 + 4 + 5)
= 12 + 42
= 54 units²
Sorry if I’m wrong but I’m saying this if area is just multiplying both numbers then if I’m correct it would be 24 but if not then it’s probably some geometry
