Question

a. Define the variable(s)
b. Write an equation to represent the situation.
c. Solve.

im stuck on how to start this

Answer 1

2 h + 2 L = 62
so
L = 31 - h

h = 2 L/3
so
L = 1.5 h

1.5 h = 31 - h
2.5 h = 31
h = 12.4
L = 18.6

Answer 2

i understand most of this, but I'm a bit confused on this part:

h = 2L/3
so
L = 31 - h

how did you get this?

Answer 3

if 2 L + 2 h = 62 given
then L + h = 31
and L = 31 - h

if h = 2L/3 given
then L = 3 h/2 = 1.5 h
