The formula for finding the lateral area for a triangular prism is

So put in the values and you get


The formula for finding the surface area of a triangular prism is
SA = bh + (s1 + s2 + s3)H
So put in all the values and you get
SA = 9(8) + (9 + 8 + 12.04)23
SA = 740
Hope this helps! :)
Given:
Width of the rectangular yard = x feet
Length of the rectangular yard = x+4 feet
Perimeter of the rectangular yard is:

Perimeter of the yard = 84 feet
To find:
The length of the rectangular yard.
Solution:
Perimeter of the yard is 84 feet.



Divide both sides by 4.


So, the width of the rectangular yard is 19 feet.
Length = 
Length = 
The length of the rectangular field is 23 feet.

There are 400 total students
.3 * 400 = 120
4.
tennis-
.1 * 400 = 40 students prefer tennis
football-
.25 * 400 = 100 students prefer football
140 students like football/tennis

400 students
There are four quarters in a whole
.25% = 100
100 * 4 = 400
