Perimeter is all sides added up together. So as you don't know a side's length you can put it as x and make an equation.
x + x + x + 6 + x + 6 = 180
4x +12 = 180
4x = 180 - 12
4x = 168
x = 168/4
x = 42
as length is 6 feet longer than width length is equal to 42 + 6 = 48 feet
You would have to share a picture or the details of this triangle in order for me to help
Answer:
6
Step-by-step explanation:
From the Trapezoid attached :
EF = GT
FG = LA
LE = AT = 10
LA = 24 ; FG = 24
FG + EF + GT = 40
Let : EF and GT = x
FG + 2x = 40
24 + 2x = 40
2x = 40 - 24
2x = 16
x = 16 ÷ 2 = 8
Hence, EF = GT = 8
Using Pythagoras :
Opposite² = hypotenus² - Adjacent²
LF² = LE² - FE²
LF² = 10² - 8²
LF² = 100 - 64
LF² = 36
LF = √36
LF = 6

F^-1(x)= (x-4)/-8 because it's just finding the inverse function
