Answer
Find out the length of the base .
To prove
Formula
Perimeter of the rectangular base = 2(Length + Breadth)
As given
Olivia wants to trim a lampshade with braid.
The lampshade is shaped like a rectangular prism.
The length of the base of the lampshade is 4 inches greater than its width.
Let us assume that the width be = x
Let us assume that the Length be = x + 4
If the perimeter of the base is 54 inches,
Put in the formula
54 = 2(x + x + 4)
54 = 2 (2x + 4)
54 = 4x + 8
54 - 8 = 4x
46 = 4x
![x = \frac{46}{4}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B46%7D%7B4%7D)
x = 11.5
Length of the base = x + 4
= 11.5 + 4
= 15.5 inches
Therefore the length of the base is 15.5 inches .

Answer:
I think it is 84 hope this helps
Answer:
x=81 degrees z=99 degrees y=68 degrees
Step-by-step explanation:
first we know 36+63+x is 180 degrees by triangle sum ( the sum of the three angles of a triangle is 180) so x would be 81 degrees. then we know x+z=180 degrees by sum of a line( a line is 180 degrees on either side) making z=99 degrees. Then doing triangle sum again we know 13+99+y=180 degrees making y=68 degrees
Add the numbers: 57 + 39 + 76 + 87 + 91 = 350;
Divide by how many numbers (i.e. we added 5 numbers): 350 ÷ 5 = 70;
<span>So the average is 70;</span>
